Answer provided by our tutors
let
p = the number of pizza slices sold
b = the number of burritos sold
the number of pizza slices sold was 20 less than twice the number of burritos sold
p = 2b - 20
pizza sold for $2.50 a slice and burritos for $3.00 each. the cafeteria collected a total of $358 for selling these two items
2.50*p + 3.00*b = 358
by solving the system of equations
p = 2b - 20
2.50*p + 3.00*b = 358
we find
p = 82 pizza slices sold
b = 51 burritos sold
