Answer for screen readers

The change Sarah receives is $8.79.

Steps to Solve

  1. Calculate the cost of green beans

Sarah buys 3 pounds of green beans, priced at $1.99 per pound.

The total cost for green beans is: $$ 3 \times 1.99 = 5.97 $$

  1. Add the cost of potatoes

The bag of potatoes costs $6.45.

Now, we add this to the green beans: $$ 5.97 + 6.45 = 12.42 $$

  1. Add the cost of the pumpkin pie

The pumpkin pie costs $8.79.

So we add this to the previous total: $$ 12.42 + 8.79 = 21.21 $$

  1. Determine the total amount paid to the cashier

Sarah gives the cashier a $20 bill and a $10 bill, totaling: $$ 20 + 10 = 30 $$

  1. Calculate the change received

Finally, we subtract the total cost of the items from the total amount given to the cashier: $$ 30 - 21.21 = 8.79 $$

The change Sarah receives is $8.79.
