Answer:

Option D. 17%

Step-by-step explanation:

we have

$f(x)=250,000(1.17)^{x}$

This is a exponential function of the form

$f(x)=a(b)^{x}$

where

a is the initial value

b is the base

In this problem

a=250,000 people

b=1.17

Remember that

b=1+r

1+r=1.17

r=1.17-1=0.17

Convert to percentage

0.17*100=17%

Let's call x1: The rate per hour of the number one mechanic. X2: The rate per hour of mechanic number two. The first thing you should do is identify the system of equations that best describes the problem. In this case it is a system of 2 equations with two unknowns which when solved gives a total of x1 = 85 $ / h and x2 = 50 $ / h. Attached solution.
