Question

In August, Cory begins school shopping for his triplet daughters. One day, he bought 3 packages of socks for $8 each and 3 pairs of shoes for d dollars each. Which pair of expressions represent the total amount Cory spent? * A. 3d + 8 and (d + 8)(d + 8)(d + 8) B. 3(d + 8) and (d + 8)(d + 8)(d + 8) C. 3d + 8 and (d + 8) + (d + 8) + (d + 8) O D. 31d + 8) and (d + 8) + (d + 8) + (d + 8) What is the value of the expression? (14 72 - 10.25); 2* 1 point​

Answer 1

D. 3(d + 8) and (d + 8) + (d + 8) + (d + 8)

II. 2.235

Explanation:

Given the following data;

3 packages at $8 each = 3 * 8 = $24

3 pair of shoes at $d each = $3d

I. To find the total amount of money Cory spent;

Total = 3d + 24

Factorizing, we have;

Total = 3(d + 8)

II. To find the value of the expression;

Your expression isn't explicitly written but I'll assume it's this;

(14.72 - 10.25)/2 =

4.47/2 = 2.235
