For the years between 2003 and 2010, the equation

ŷ = 937.98x + 12, 764.90 models the average cost of tuition of four-year colleges, in dollars, where X is the number of years after 2000. What is the best estimate for the average cost of tuition in 2005? Enter your answer in the box. Round to the nearest dollar.

Answer: $ 17,455

Step-by-step explanation:

Hi, to answer this question, first we have to calculate the years passed between 2000 and 2005.

Mathematically speaking:

2005-2000 = 5 years

Next, we have to substitute x = 5 in the equation given

ŷ = 937.98x + 12, 764.90

ŷ = 937.98 (5) + 12, 764.90

ŷ = 4,689.9 + 12, 764.90

ŷ = 17,454.8

ŷ = $ 17,455 (rounded to the nearest dollar)
