To calculate how much Thomas owed and how much change he should receive, we need to determine the cost of his order before tax. However, the price list is not provided in the question.
Assuming you have access to the prices:
-
Let’s define the prices as follows (example prices):
- Doughnut holes: $X per order
- Cinnamon roll: $Y
- Doughnuts: $Z each
-
Now, using the quantities Thomas ordered:
- 2 orders of doughnut holes: 2 * X
- 1 cinnamon roll: 1 * Y
- 3 doughnuts: 3 * Z
So the subtotal before tax would be: \[ \text{Subtotal} = (2 \times X) + (1 \times Y) + (3 \times Z) \]
-
The sales tax is given as $0.72, so the total amount Thomas owed would be: \[ \text{Total} = \text{Subtotal} + \text{Sales tax} = [(2 \times X) + (1 \times Y) + (3 \times Z)] + 0.72 \]
-
To find out how much change Thomas should receive, we subtract the total from the amount he paid ($20): \[ \text{Change} = 20 - \text{Total} \]
With the actual prices for the doughnut holes, cinnamon rolls, and doughnuts, you can plug in \(X\), \(Y\), and \(Z\) to find Thomas's total.
If you provide the prices, I can help calculate the exact total and change amount.
