Agata [3.3K]

Answer: x = $11,900

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Joshua’s earnings: g(x)=175+0.05x

Caleb's earnings: f(x)=532+0.02x.

So, if both earnings are equal:

g(x) =f (x)

175+0.05x =532+0.02x

Solving for x:

0.05x-0.02x = 532-175

0.03x= 357

x = 357 /0.03

x = $11,900

Feel free to ask for more if needed or if you did not understand something.
