Explanation / Answer

Let y denote total cost in dollars.

x denote number of months.

The equation is,

y = 20 + 70x

Here b0 = 20

b1 = 70

Now we have to predict y for 3,12,15.

We can find y by using this equation by putting x value.

x = 3,

y = 20 + 70x

y = 20 + 70*3 = 230

x = 12,

y = 20 + 70*12 = 860

x = 15,

y = 20 + 70*15 = 1070

x y 3 230 12 860 15 1070
