Question

A tennis coach took his team out for lunch and bought 8 hamburgers and 5 fries for $24. The players were still hungry so the coach bought 6 more hamburgers and 2 more fries for $16.60. Find the cost of each.

Answer 1

8x+5y=$24
6x+2y=$16.60

16x+10y=$48
-30x-10y=-$83

-14x=-$35
x=$2.50

8($2.50)+5y=$24
$20.00+5y=$24
5y=$4
y=$0.80

Hamburgers costs $2.50 each
Fries cost $0.80 each
