1. The total bill including sales tax is <u>$34.72</u>.
2. The amount the purchaser should pay the cashier is <u>$34.72</u>.
3. The denominations for the payment should be one $20 bill, one $10 bill, four $1 bills, and 72 cents (pennies).
<h3>How is the total cost determined?</h3>
The total cost payable to the grocery store cashier is the cost of the groceries plus the sales tax.
The cost for groceries = $32.75
Sales tax = 6%
Total cost = cost plus sales tax
= $34.72 ($32.75 x 1.06)
We can check the sum as follows:
Unit Bill Amount
1 $20 $20
1 $10 10
4 $1 4
Cents 0.72
Total $34.72
Thus, the grocery purchaser will be spending <u>$34.72</u>, including the sales tax.
