REVIEW: Brinlyn increased the amount of water she drank per day from 32 oz to 40 oz. By what percentage did Brinlyn increase the amount of water she drank each day?
percent change = amount of change/original amountâ‹…100
Let's calculate the percentage increase in the amount of water Brinlyn drank each day.
Original amount of water = 32 oz
New amount of water = 40 oz
Amount of change = New amount - Original amount = 40 oz - 32 oz = 8 oz
Percentage increase = (Amount of change / Original amount) * 100
= (8 oz / 32 oz) * 100
= (1/4) * 100
= 25%
Therefore, Brinlyn increased the amount of water she drank each day by 25%.
REVIEW: A television normally sells for $320. This week, it is on sale for 60% off the normal price. What is the sale price?
To find the sale price of the television, we need to calculate the discount amount and subtract it from the normal price.
Normal price of the television = $320
Discount percentage = 60%
Discount amount = Discount percentage * Normal price
= 60% * $320
= 0.60 * $320
= $192
Sale price = Normal price - Discount amount
= $320 - $192
= $128
Therefore, the sale price of the television is $128.
Suzanne earns $300 per week plus $15 per sale at her job. She is hoping to make AT LEAST $600 this week. How many sales will she need to make? Suzanne writes the inequality 15x+300≥600
, where x = the number of sales. Solve the inequality.
To solve the inequality 15x + 300 ≥ 600, we need to isolate the variable x.
Subtract 300 from both sides of the inequality:
15x ≥ 600 - 300
15x ≥ 300
Now, divide both sides of the inequality by 15:
x ≥ 300/15
x ≥ 20
Therefore, Suzanne will need to make at least 20 sales in order to earn at least $600 this week.
okay here are the option to the question
1. x ≥ 60
2. x ≥ 20
3. x ≥ 4500
4. x ≥ 1.95
My apologies for the confusion. The correct answer is option 2.
The correct inequality is 15x + 300 ≥ 600, and when solved, it gives x ≥ 20.
So Suzanne will need to make at least 20 sales in order to earn at least $600 this week.
