The given regression shows the relationship between the numbers of car washed(x) and the amount earned for charity(y).

y = 10x + 20

We are to calculate the amount of charity if 50 cars are washed. Number of cars are represented by x, so by substituting x = 50 in above equation we can find the amount of charity that is earned by washing 50 cars.

y = 10(50) + 20 = $ 520

Thus, the charity can earn $520 if 50 cars come in for a wash.

GREYUIT [131]

The answer should be D since after 5 am to 7 am only two hours have passed so x=2, and then you plug in the x as 2 and solve it. You might get not around answer like 39.785 but when you round it, it would be 40.
