Final answer:
To find the total purchase price, add the cost of the items and the sales tax together. The total purchase price is $84.65.
Step-by-step explanation:
To find the total purchase price, we need to calculate the sales tax for each item and then add it to the cost of the items.
- The sales tax for the deluxe dictionary is 6% of $38.75, which is $2.33.
- The sales tax for the full-color atlas is 6% of $41.10, which is $2.47.
Now, add the cost of the items and the sales tax together:
$38.75 + $2.33 + $41.10 + $2.47
= $84.65
Therefore, the total purchase price is $84.65.
