Answer 1

Let's calculate the total cost of Thomas's order first:

1. Doughnut holes:

   • Price per order: $1.75
   • Thomas ordered 2 orders: \[ 2 \times 1.75 = 3.50 \]

2. Cinnamon roll:

   • Price: $2.59
   • Thomas ordered 1: \[ 2.59 \]

3. Doughnuts:

   • Price per doughnut: $0.95
   • Thomas ordered 3 doughnuts: \[ 3 \times 0.95 = 2.85 \]

Now, let's sum these costs:

\[ \text{Total cost before tax} = \text{Doughnut holes} + \text{Cinnamon roll} + \text{Doughnuts} \] \[ \text{Total cost before tax} = 3.50 + 2.59 + 2.85 = 8.94 \]

Now, we add the sales tax:

\[ \text{Total amount owed} = \text{Total cost before tax} + \text{Sales tax} \] \[ \text{Total amount owed} = 8.94 + 0.72 = 9.66 \]

So, Thomas owed $9.66.

Next, let's calculate the change Thomas should receive after paying with a $20 bill:

\[ \text{Change} = \text{Amount paid} - \text{Total amount owed} \] \[ \text{Change} = 20.00 - 9.66 = 10.34 \]

In summary:

• Thomas owed $9.66.
• Thomas should receive $10.34 in change.
