The equations 6x + 5y = 300 and 3x + 7y = 285 represent the
money collected from selling gift baskets in a school fundraising
event. if x represents the cost for each snack gift basket and
y represents the cost for each chocolate gift basket, what is the cost
for each chocolate gift basket?
(1) $20 (3) $30
(2) $25 (4) $54
