Help please i will give 30 points
Nata [24]

Answer:

C. 7h + 50 > 99

Step-by-step explanation:

She earns <u>more</u> than $99, so you know that the sign will be > (more than).

h is the number of hours, so to find how much she earns for working h hours at $7/hour, you multiply h by 7  ---  7h

She also earns an additional $50, which will be +50.

Therefore, the equation is: 7h + 50 > 99

Hope this helps :D
