Question

Felipe's earnings vary directly with the number of hours he works. Suppose that he worked 6 hours yesterday and earned $84. How much will he earn today if he works 5 hours?

Answer 1

Answer:

70$

Step-by-step explanation:

We know that he earned $84 for 6 hours of work yesterday. Let's call his earnings E.

Let's use the direct variation formula:

earnings1/hours1 = earning2/hours2

Substitute

84/6 = E/5

Let's solve for E

14/1 = E/5

E = 14x5

E = 70

Therefore, if Felipe works 5 hours today, he will earn $70.
