A computer company uses the linear model y = -21x + 13,082 to predict the decline in sales of a computer after it has been on the market more than one year. If x is the number of months after the first year and y is the number of computers sold during that month, how many computers will be sold 11 months after the first year?

you have to plug in 11 for x since x is the number of months so when you plug it in you would rewrite the equation as y=-21(11)+13082. Then you would solve for y. -21 x 11 is -231. -231 + 13082 = 12851 computers sold in 11 months after the first year. :) hope this helps
