Isabel earns $7.50 per hour on the weekends. Write and solve an inequality to find how many hours she needs to work to earn at least $120.

A few things to note:

• Earnings = Rate * time
• Let h be the number of hours worked
• The phrase at least means greater than or equal to, so we have the following inequality.

We represent this with the following inequality:
7.5h < 120

To solve this inequality for h, we type it into our math engine and we get:
h < 16
