Question

Geeta, Richard, and Steve are all computer repair technicians. The equation, graph, and table shown represent the amount of pay (p) in dollars they each receive as a function of the number of hours (h) a computer repair takes. Study each of the functions and then answer the question using complete sentences.

Who earns the most per hour? Explain how you found the answer.

Answer 1

Geeta earns most per hour.

Explanation:

From the question:

Geeta earns

p = 75 +45h

where p is the amount Geeta earns by working for h hours

So For 1 hour geeta earns

p = 75 +45(1)

p = 75+45

p =120

From the graph:

we can find for each hour the pay increases 30 dollars for each work

So, its clear that Richard earns 30 dollars per hour

The table shows that

Steve earns $110 every 2 hour

So for one hour Steve will be earning 55 dollars

Pay of Geeta > Pay of Steve > Pay of Richard

i.e.,

120 > 55 > 30
