Answer:

A) $3

B) $20

Explanation:

First, find the cost of the pizza slice.

If she gave the lunch lady $10 and received $7 back, the pizza slice was $3.

This cost would give her $7 from the $10 that she paid.

Now, find how much money Susie needs.

Since each pizza slice is $3, we can find how much money the pizza will cost by multiplying 5 by 3:

5(3)

= 15

Add 5 to this, since the soda is $5

15 + 5

= 20

So, Susie will need $20
