Question

Fabio paid $15.50 for five slices of pizza and two sodas. Liam paid $19.50 for six slices of pizza and three sodas. How much does each slice of pizza costs?

Answer 1

 $19.50
-$15.50=
$4.00
1slice of pizza and 1soda is $4
so 2slices of pizza and 2 sodas is $8
$15.50-$8=$7.50
Now you have 3 slices of pizza left
$7.50/3slices=$2.50
1slice of pizza is $2.50
