At an Italian bistro, the cost of 2 plates of spaghetti and 1 salad is $27.50. The cost for 4 plates of spaghetti and 3 salads is $59.50. Write and solve a system of equations to find the cost of 1 plate of spaghetti and 1 salad.
Answer provided by our tutors
let
x = the cost of 1 plate of spaghetti
y = the cost of 1 salad
the cost of 2 plates of spaghetti and 1 salad is $27.50:
2x + y = 27.50
The cost for 4 plates of spaghetti and 3 salads is $59.50:
4x + 3x = 59.50
by solving the system of equations:
2x + y = 27.50
4x + 3x = 59.50
we find:
x = $8.50
y = $10.50
