Chloe got a $25 gift card to an online music store. She uses the gift card to buy an album for $5.99. She also wants to use the gift card to buy some songs. Each song costs $.99.
​Which of these inequalities describes this situation, where n is the number of songs Chloe wants to buy?

• 5.99 + .99n ≥ 25

• 5.99 + .99n ≤ 25

• 5.99 - .99n ≥ 25

• 5.99 - .99n ≤ 25

Gabby purchases a lawn mower for $200 so she can start mowing lawns for money. She plans to charge $40 for each yard she mows. Let y represent the number of yards Gabby mows. Select the inequality which can be used to determine the number of yards Gabby must mow in order to cover the cost of the lawn mower and earn a profit of more than $500.

• 40y - 200 > 500

• 40y - 500 > 200

• 40y + 200 > 500

• 40y + 500 > 200
