At the market, 5 light bulbs cost $9.
How much do 7 light bulbs cost?
plzz help I am doing a Unit Test!.
First, find the cost of one light bulb:
$9/5 = $1.80
Then, multiply the cost of one light bulb by 7:
$1.80 x 7 = $12.60
Therefore, 7 light bulbs would cost $12.60.

2. Sophie Ruth is eating a 50- gram chocolate bar which contains 30% cocoa.
How many grams of cocoa are in the chocolate bar?
To find out how many grams of cocoa Sophie's chocolate bar contains, multiply the grams of the chocolate by the percentage of cocoa:
50 grams x 30% = (50 x 30) / 100 = 15 grams
Therefore, there are 15 grams of cocoa in Sophie's chocolate bar.
Thanks.. Meesheell.!
You're welcome! Do you have another question?
Yeah I still have 7 but I am trying to figure out how to multiply the percents...
To multiply percents, you'll need to convert them to decimals first, then multiply the decimals together, and finally convert the product back to a percent.
For example, let's say you need to multiply 25% and 20%. Here's how that would look using the steps I just mentioned:
1. Convert the percents to decimals:
- 25% = 0.25
- 20% = 0.20
2. Multiply the decimals together:
- 0.25 x 0.20 = 0.05
3. Convert the product back to a percent:
- 0.05 = 5%
So, 25% multiplied by 20% is equal to 5%.
ohh now I understood thanks,..
so can you help me with this new question?
Sure, I'm happy to help. Please go ahead and ask the next question.
3. The tape diagram shows the Shanice spent 120 minutes researching for debate club last week.
Complete the table to show different percentages of Shanice's
research time.
Time (min) Percentage
? = 100% of 120 min
? = 10% of 120 min
? = 110% of 120 min
Here's a table that shows the different percentages of Shanice's research time:
| Time (min) | Percentage |
|------------|----------------|
| 120 | 100% of 120 min |
| 12 | 10% of 120 min |
| 132 | 110% of 120 min |
To find the missing values in the table, you can use the following formulas:
- To find 10% of 120 minutes, divide 120 by 10:
10% of 120 min = (10/100) x 120 min = 12 min
- To find 110% of 120 minutes, add 10% to 100%:
110% of 120 min = 100% of 120 min + 10% of 120 min = 120 min + 12 min = 132 min
Therefore, the table is complete with the values for each percentage.
Thanks..!!
You're welcome! Do you have another question?
Yeah...
Please go ahead and ask.
4. Which of the following options have the same value as 10% of 33?
Choose 3 answers;
1. 0.1 ✖ 0.33
2. 10 ✖ 33
3. 1/10 ✖ 33
4. 0.1 ✖ 33
5. 10/100 ✖ 33
To find which options have the same value as 10% of 33, you can start by calculating 10% of 33 using the following formula:
10% of 33 = (10/100) x 33 = 3.3
Then, you can check which options have the same value as 3.3:
1. 0.1 x 0.33 = 0.033 - NOT the same
2. 10 x 33 = 330 - NOT the same
3. 1/10 x 33 = 3.3 - SAME
4. 0.1 x 33 = 3.3 - SAME
5. 10/100 x 33 = 3.3 - SAME
Therefore, options 3, 4, and 5 have the same value as 10% of 33.
Thank you very much Meesheell..!!!!
You're welcome! Do you have another question?
Yeah but I can do it myself... On the other question okay..?
Sure, no problem. If you need any further assistance, feel free to ask. Good luck with your test!
8. Brenda can deliver 644 newspapers in 7 hours.
How many newspapers can Berenda deliver in 9 hours?
To find out how many newspapers Brenda can deliver in 9 hours, you can use proportional reasoning.
Brenda can deliver 644 newspapers in 7 hours, so she can deliver:
644/7 = 92 newspapers per hour
Therefore, in 9 hours, Brenda can deliver:
92 x 9 = 828 newspapers
Therefore, Brenda can deliver 828 newspapers in 9 hours.
Thanks this is the last question on te Unit Test/.///
HELP.!!!!!
No problem, I'm here to help. Please go ahead and ask your last question.
The double number line shows that Jessica lives 48km from the capitol.
Complete the table to show different percentages of the distance.
Distance (km) Percentage
48 = ?% of 48 km
12 = ?% of 48 km
60 = ?% of 48 km
Here's a table that shows the different percentages of Jessica's distance from the Capitol:
| Distance (km) | Percentage |
|---------------|----------------|
| 48 | 100% of 48 km |
| 12 | 25% of 48 km |
| 60 | 125% of 48 km |
To find the missing values in the table, you can use the following formulas:
- To find the percentage that a distance represents of 48 km, divide the distance by 48 and multiply by 100:
percentage = (distance / 48) x 100
- To find percentages greater than 100%, you can add 100% and the additional percentage together:
125% of 48 km = 100% of 48 km + 25% of 48 km = 48 km + 12 km = 60 km
Therefore, the table is complete with the values for each percentage.
Thanks I got a 100%!!! YAY thanks Meesheell!

4. Heather is a cashier. She can ring up 12 customers in 9 minutes.
At this rate, how many minutes does it take her to ring up 4 customers?
To solve this problem, you can use proportional reasoning.
Heather can ring up 12 customers in 9 minutes, so she can ring up:
- 4 customers in (9/12)*4 = 3 minutes.
Therefore, it takes Heather 3 minutes to ring up 4 customers at this rate.
Thanks..
You're welcome! Do you have another question?
Yeah... I still have 4 more..
Alright, just let me know what your next question is.
