Answer provided by our tutors
let
x = the number of hamburger buns
y = the number of hot dog bus
the Harlin family is bringing 12 packages of buns
x + y = 12
the total cost of the contribution is $20
2x + 1.5y = 20
by solving the system of equations
x + y = 12
2x + 1.5y = 20
we find
x = 4 hamburger buns
y = 8 hot dog buns
