Answer:
One piece of pizza = $2.5
One candy bar = $1
Step-by-step explanation:
Call 1 pizza a, 1 candy bar b. We have:
2a + 3b = $8
=> 3(2a+3b) = 3. $8
= 6a + 9b = $24
and
6a + 5b = $20
=> (6a + 9b) - (6a + 5b) = 9b - 5b = 4b = $24 - $20 = $4
=> b = $1
=> 2a + $3 = $8
=> 2a = $5
=> a = $2.5
So one piece of pizza = $2.5, one candy bar = $1
