Question 222 points

Solve the problem.

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?

Explanation / Answer

1.Let the person’s emotional age be x years. Since emotional quotient (EQ) is found by multiplying emotional age by 100 and dividing by chronological age, and since the person’s chronological age is 21 years, hence x*100/21 = 97 so that x = 97*21/100 = 20.37. The 3rd option is the correct answer.

2.The linear model y = -21x + 13-231+13082 predicts the decline in sales of a computer after it has been on the market more than one year where x is the number of months after the first year and y is the number of computers sold during that month. When x = 11, we have y = -21*11 + 13082   = -231+ 13082 =12851. The 1st option is the correct answer.
