Final answer:
To find out how many stamps Kwasi can buy for $22, divide the total amount by the cost of one stamp ($0.55).
Step-by-step explanation:
To find out how many stamps Kwasi can buy for $22, we first need to determine the cost of one stamp. We can do this by dividing the total cost of 15 stamps ($8.25) by the number of stamps.
$8.25 / 15 = $0.55 per stamp.
Next, we can calculate how many stamps Kwasi can buy for $22 by dividing the total amount by the cost of one stamp.
$22 / $0.55 = 40 stamps.
Therefore, Kwasi can buy 40 stamps for $22.
