7. The grocery store sells a 25-ounce container of lemonade mix for $2.00. The wholesale club sells a 75-ounce container of the same lemonade mix for $6.75.

a) Find the unit price for the lemonade mix at the grocery store.

b) Find the unit price for the lemonade mix at the wholesale club.

c) Where should you buy the lemonade mix if you want the better deal? Explain. (3 points)

8. Convert the map scale to a unit rate. How many inches represent one mile? Show your work. Interpret the meaning of the unit rate.

these answers are 100000% percent correct I just took the assessment.

1.A
2.C
3.A
4.B
5.B
6: Ratio 1: 60/45
Ratio 2: 60:45
Ratio 3: 60 of 45
7:X - the price per oz in the grocery store
y - the price per oz in the wholesale club

a) The answer is $0.031 per oz
He can buy 64 fl oz at the grocery store for $2.00:
64x = 2
x = 2 / 64
x = $0.031

b) The answer is $0.029 per oz
He can buy 256 fl oz at the wholesale club for $7.50:
256y = 7.50
x = 7.50 / 256
x = $0.029

c) The answer is wholesale club

Let's calculate where you can get more oz for $1 using the proportion.
Grocery store:
1 oz for $0.031
x oz for $1
1 : 0.031 = x : 1
x = 1 * 1 : 0.031
x = 32.26 oz

Wholesale club:
1 oz for $0.029
x oz for $1
1 : 0.029 = x : 1
x = 1 * 1 : 0.029
x = 34.48 oz

34.48 oz > 32.26 oz, so he should buy at the wholesale club

8:3/10 in = 7/8 ft
(3*8) / (10*7) in = 1 ft
24 / 70 in = 1 ft
0.3428 in = 1 ft

divide both sides by 0.3428

1 in = 2.917 ft
63,360 in are in a mile.

How would you like us to help you?

I need help with this quiz too

i know the first one is a

im stuck on this too, guys please help...

thank you

i need help on quiz part two

1. To find the ratio of the number of school signs to the number of stop signs, we need to divide the number of school signs by the number of stop signs. Given that there are 9 school signs and 24 stop signs, the ratio is 9:24.

2. To find the equivalent ratio of four over sixteen, we need to simplify it by finding the greatest common divisor (GCD) of the numerator and denominator. In this case, the GCD of 4 and 16 is 4. Dividing both the numerator and denominator by 4 gives us 1 over 4, which is equivalent to the ratio 1:4.

3. To write the ratio of 8 meters in 10 seconds as a unit rate, divide the distance (8 meters) by the time (10 seconds). This gives us 0.8 meter per second.

4. To write the ratio of 27 miles in one-half hour as a unit rate, divide the distance (27 miles) by the time (0.5 hour). This gives us 54 miles per hour.

5. To compare the reading rates of Carla, Josh, and Malik, we need to calculate the number of pages they read per minute.

- Carla reads 45 pages in 90 minutes, which gives us a reading rate of 0.5 pages per minute.
- Josh reads 28 pages in 56 minutes, which gives us a reading rate of 0.5 pages per minute.
- Malik reads 67 pages in 134 minutes, which gives us a reading rate of 0.5 pages per minute.

Therefore, Carla, Josh, and Malik all have the same reading rate.

6. The ratio of the time Pam spends driving home from work to the time she spends driving to work can be expressed in three different ways:
- 60 minutes:45 minutes
- 4:3
- 4/3

7. a) To find the unit price for the lemonade mix at the grocery store, divide the total cost ($2.00) by the number of ounces (25). This gives us a unit price of $0.08 per ounce.

b) To find the unit price for the lemonade mix at the wholesale club, divide the total cost ($6.75) by the number of ounces (75). This gives us a unit price of $0.09 per ounce.

c) The better deal is at the grocery store, where the unit price is lower ($0.08 per ounce) compared to the wholesale club ($0.09 per ounce).

8. To convert the map scale to a unit rate, we need to determine how many inches represent one mile. For example, if the map scale is 1 inch:100 miles, then the unit rate is 1 inch per 100 miles. This means that on the map, 1 inch represents a distance of 100 miles. The unit rate represents the relationship between the map scale and the actual distance in real life.
