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.

Answer 1

To solve the inequality, we can start by subtracting 300 from both sides to isolate the 15x term:
15x + 300 - 300 ≥ 600 - 300
15x ≥ 300
Next, divide both sides by 15 to solve for x:
(15x) / 15 ≥ 300 / 15
x ≥ 20
Therefore, Suzanne will need to make at least 20 sales in order to make at least $600 this week.

REVIEW: A television normally sells for $320. This week, it is on sale for 60% off the normal price. What is the sale price?(1 point)

Answer 3

To find the sale price, we need to calculate 60% of the normal price and subtract it from the normal price.

First, we find 60% of $320 by multiplying 320 by 0.60:

320 * 0.60 = $192

Next, we subtract this amount from the normal price to find the sale price:

320 - 192 = $128

Therefore, the sale price of the television is $128.

Answer 4

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 changeoriginal amount⋅100

Answer 5

To find the percentage increase, we can use the formula:

percent change = (amount of change / original amount) * 100

In this case, the amount of change is 40 oz - 32 oz = 8 oz.

The original amount is 32 oz.

So, the percentage increase is:
(8 oz / 32 oz) * 100 = 25%

Therefore, Brinlyn increased the amount of water she drank each day by 25%.

Answer 6

REVIEW: Candace purchased 6 gallons of gas for $13.56. What is the constant of proportionality that relates the cost in dollars, y, to the number of gallons, x?

Remember, the constant of proportionality is k=y/x .

Answer 7

To find the constant of proportionality that relates the cost in dollars, y, to the number of gallons, x, we can divide the cost by the number of gallons.

k = y / x

In this case, the cost is $13.56 and the number of gallons is 6.

k = 13.56 / 6 = 2.26

Therefore, the constant of proportionality that relates the cost in dollars to the number of gallons is 2.26.

Answer 8

What is the constant of proportionality that relates Matthew's earnings, y, to the number of hours he worked, x?

Remember, the constant of proportionality is k=y/x and can be found using any point on the line.

Answer 9

To find the constant of proportionality that relates Matthew's earnings, y, to the number of hours he worked, x, we can use any point on the line.

Let's say Matthew earned $60 for working 5 hours. We can use this point (5, 60) to find the constant of proportionality.

k = y / x

In this case, y = $60 and x = 5.

k = 60 / 5 = 12

Therefore, the constant of proportionality that relates Matthew's earnings to the number of hours he worked is 12.
