Final answer:
The total purchase price, including sales tax, for the two blankets, one mattress, and one sheet that Mike purchased is $178.69.
Step-by-step explanation:
To work out the total purchase price, including sales tax, for the items Mike purchased, first, we need to calculate the total cost of the blankets, mattress, and sheet before tax:
- Two blankets: 2 × $44.99 each = $89.98
- One mattress: $59.00
- One sheet: $19.99
Add these amounts together to find the subtotal:
$89.98 + $59.00 + $19.99 = $168.97
Next, we compute the sales tax. Convert the percent to a decimal by moving the decimal point two places to the left (5.75% becomes 0.0575), and then multiply by the subtotal:
0.0575 × $168.97 = $9.7161
Round the sales tax to the nearest cent: $9.72
Finally, add the sales tax to the subtotal to get the total purchase price:
$168.97 + $9.72 = $178.69
Therefore, the total purchase price, including sales tax, is $178.69.
