This is a problem involving ratios. First find the ratio of dollars to sweaters. That means, how much would just 1 sweater cost if 4 sweaters cost $51.04?
.
if 4 sweaters cost $51.04:
$51.04 / 4 sweaters = $12.76 / 1 sweater
.
Since one sweater costs $12.76, multiply this by 6 sweaters and you get:
.
how much would 6 sweaters cost?
$12.76 x 6 sweaters = $76.56
