Sylvia needs at least $310 for a new audio system. she has already saved 120$. she earns 10$ per hour at her part time job. write and solve an inequality to find how many hours she will need to work to buy the system. interpret the solution.

310 = 120 + 10x

Step-by-step explanation:

310 represents the final number she needs to by the audio system

120 represents the money she has already saved

10 represents the amount of money she will earn in x amount of hours; multiplied by x

Example, if she worked 2 hours;

310 = 120 + 10(2)

310 = 140

She would have to work more obviously to meet the $310 criteria
