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? Only 4 digits/variables can be used.

Respuesta :

$24+$5n=$39
because the 2 purses equal a total of $24
Or even more simplified: $5n = $15
n = 3
5n+24=39 because you already know how many purses Rebecca purchased but if that's not correct then it's 5n+12p=39
