Richard bought 3 slices of cheese pizza and 2 sodas for a total of $12. If each slice of pizza costs $3, how much does each soda cost?

Richard spent $12 on 3 slices of cheese pizza and 2 sodas. Since each slice of pizza costs $3, we can calculate the total cost of the pizza:

3 slices × $3 = $9

Subtracting this from the total:

$12 – $9 = $3

This means the cost of 2 sodas is $3. To find the cost of one soda:

$3 ÷ 2 = $1.50

So, each soda costs $1.50. This simple calculation shows how to break down total costs when you know the price of some items.
