Question

Rebecca's buys some scarves that costs $5 each and 2 purses that cost $12 each. The cost of Rebecca's total purchase is $39. What equation can be used to find n, the number of scarves that Rebecca buys?

Answer 1

Scarves = 3

$39 = 5n + 2(12)$
$15 = 5n$
n = 3

Answer 2

X=number of scarves
5x+2·12=39
5x+24=39
5x=39-24
5x=15
x=15:5
x=3 scarves

Answer:3
