A store sells 5 notebooks at 2 dollars and 49 cents each and 3 pens at 1 dollar and 25 cents each. You pay with 20 dollars. How much change do you receive?
First, let's calculate the total cost of the notebooks. We need to multiply 5 by 2 dollars and 49 cents. Five times 2 dollars and 49 cents equals 12 dollars and 45 cents.
Next, let's calculate the total cost of the pens. We need to multiply 3 by 1 dollar and 25 cents. Three times 1 dollar and 25 cents equals 3 dollars and 75 cents.
Now we add the cost of notebooks and pens to find the total purchase amount. 12 dollars and 45 cents plus 3 dollars and 75 cents equals 16 dollars and 20 cents.
Finally, we subtract the total purchase amount from the payment to find the change. 20 dollars minus 16 dollars and 20 cents equals 3 dollars and 80 cents.
Let's review all the steps. Five notebooks at 2 dollars and 49 cents each cost 12 dollars and 45 cents. Three pens at 1 dollar and 25 cents each cost 3 dollars and 75 cents. The total purchase is 16 dollars and 20 cents. With a payment of 20 dollars, the change is 3 dollars and 80 cents. We can verify this by adding the total purchase and change, which equals our payment of 20 dollars.
