Answer provided by our tutors
let
s = the number of small size orders
j = the number of jumbo size orders
37 orders of fries
s + j = 37
french fries were sold at 80 cents = $0.80 small size and at $1.50 for jumbo size a total of $42.20
0.80s + 1.50j = 42.20
by solving the system of equations
s + j = 37
0.80s + 1.50j = 42.20
we find
s = 19 small size fries
j = 18 jumbo size fries
