Sagot :

Answer: 13.7636

The value is approximate. Round it however you need to.

====================================================

Explanation:

x = number of years

y = cost

The teacher wants to know what value of x will make y = 2500.

Plug it in and solve for x.

y = 134.02x + 655.40

2500 = 134.02x + 655.40

2500-655.40 = 134.02x

1844.6 = 134.02x

x = 1844.6/134.02

x = 13.7636 approximately

Somewhere between year 13 and 14 is when the price should be $2500. This is of course based on the regression line estimate which isn't perfect.
