(d) Estimate the total revenue for Costco Wholesale Corporation in 2012. (Round your answer to one decimal place.)

Answer 1

a) (64,400 - 48,100)/(5 - 2) = 16300/3 = 5833.33

Plug in either "point."

48,100 = 5833.33(2) + b

48,100 = 10,866.66 + b

b = 37,233.3

y = 5833.33x + 37233.3

b) y = 5833.33(10) + 37233.3

y = 95,566
