Answer:
Cost of pop = $2
Cost of snacks = $3
Step-by-step explanation:
Let
Cost of pop = x
Cost of snacks = y
Hauler
x + 4y = 14
Good
2x + 2y = 10
x + 4y = 14 (1)
2x + 2y = 10 (2)
Using elimination method
Multiply (1) by (2)
2x + 8y = 28 (3)
2x + 2y = 10 (2)
Subtract (2) from (3) to eliminate x
8y - 2y = 28 - 10
6y = 18
y = 18/6
y = $3
Substitute y = 3 into (1)
x + 4y = 14 (1)
x + 4(3) = 14
x + 12 = 14
x = 14 - 12
x = $2
Cost of pop = $2
Cost of snacks = $3
