Step-by-step explanation:
Answer:
a) 150-90 = h(15.25 -9.75)
b) 10.91
Step-by-step explanation:
a) Jennifer has 150 -90 = 60 less in savings than Eduardo, but she is earning 15.25 -9.75 = 5.50 more per hour. An equation she can use to figure her hours is ...
60 = 5.50h . . . . for h hours worked.
In 'raw' form, that might be ...
150 -90 = (15.25 -9.75)h
__
b) Solving the above equation, we get ...
60/5.50 = h ≈ 10.90909 ≈ 10.91 . . . hours
