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
