Question

Shirley wants to buy a skateboard for $64. She has $98 in her account. She spent $10.85 to buy stationary. She also wants to buy some cookies for $1.65 each. What is the maximum number of cookies, n, that Shirley can buy so that she has enough money left to buy the skateboard? (1 point) n ? 16 n ? 14 n ? 14 n ? 16v

Answer 1

she can buy 14 cookies. the answer is 14 n

Answer 2

Subtract cost of stationary from total in account

98 - 10.85 = 87.15

Subtract cost of skateboard from new total

87.15 - 64 = 23.15

Set up an algebraic expression

23.15 = 1.65x

Divide each side by 1.65 to isolate x

x = 14.0303 or 14
