Question

Erin went to the grocery store and bought 2 pounds of apples, 3 pounds of oranges and 1 pound of bananas. If sales tax for her order was $0.91 and Erin paid with a $20 bill, how much change did she receive?

Answer 1

For this problem, we are given the prices of apples, oranges, and bananas. We are also told how much the tax for a certain order was and the amounts. We need to calculate how much change was received for a 20$ bill.

The first step is to calculate the total amount of the purchase.

`\begin{gathered} cost=2\cdot2.79+3\cdot2.19+1\cdot0.79+0.91\\ \\ cost=5.58+6.57+0.79+0.91\\ \\ cost=13.85 \end{gathered}`

Now we need to subtract this value from 20.

`change=20-13.85=6.15`

The change should be $6.15.
