Question

Jake has a applies. First he gives 24 away to the students in his math class. Then he divides the rest of the apples equally among his 3 sisters. Write the expression that represents the number of apples that each of his sisters receives.

In an online media store, downloaded songs cost $3d each and books cost $9b each. Caleb purchased 15 songs and 3 books this month, and also paid $7 in sales tax. Write and simplify an expression to show how much Caleb spent on everything including tax.


thx ;)

Answer 1

(a-24)/3

(15 * 3 + 3 * 9) + 7
= 45 + 27 + 7
= 79

Answer 2

1. (a-24)/3

2. (3 x 15) + (3 x 9) + 7
= 3(15 + 9) + 7
= 3 x 24 + 7
= 84 + 7
= 91

Hope this helps!
