romeo makes $12.00 an hour for his first hour of work, $17.00 his second hour, $22.00 his third hour and so on. How much money in total will he have earned after his 50th hour of work?

Respuesta :

Step-by-step explanation:

This can be modeled by the equation f(x)=7+5x

Because if f(1)=7+5=12, f(2)=7+10=17, and f(x)=7+15=22

If x=50 then f(50)=7+5(50)

f(50)=$257
