Answer:
$3.78
Step-by-step explanation:
Given: The first group bought 6 slices of pizza and 4 soft drinks for $ 28.28.
The second group bought 5 slices of pizza and 4 soft drinks for $ 24.50.
To find: The cost of one slice of pizza.
Solution: Let the cost of one slice of pizza be $ x, and the cost of one soft drink be $ y.
As per question,
[tex]6x+4y=28.28[/tex] ...(1)
[tex]5x+4y=24.50[/tex] ...(2)
On subtracting equation 2 from 1 we have,
[tex]x=28.28-24.50[/tex]
[tex]x=3.78[/tex]
Hence, one slice of pizza costs $3.78.
