Question

A computer engineer is paid $20 per hour and $12 for coming to work on time. How many hours must she work to earn a minimum of $172?

Answer 1

Answer:

8 hours

Step-by-step explanation:

Let x = the hours she work

Equation-

1.  20x + 12 = 172

2.         - 12   - 12

     20x = 160

3.   /20    /20

4.  x= 8 hours

1. Write out the equation

2. subtract 12 from both sides

3. Divide 20 on both sides

4. Your answer is 8 hours
