Answer:

$50

Explanation:

Hello There!

We are given that for 1 hour of work 250 dollars is charged and for 3 hours of work 350 dollars is charged

This could also be represented in two points (1,250) and (3,350)

The question wants us to find the hourly charge rate (slope)

we can easily find the slope ( hourly charge rate ) by using the slope formula


slope=(y_2-y_1)/(x_2-x_1)

we have our two points so all we need to do is plug in the values (remember y values go on top and x values go on the bottom.)


slope=(350-250)/(3-1) \\350-250=100\\3-1=2\\slope=(100)/(2) or50

So we can conclude that the hourly charge rate is $50
