Answer:
The total cost of the wallet = $34.35
Step-by-step explanation:
Cost price of the wallet = $31.95
Sales tax on the price of the wallet = 7.5%
We need to find the total cost of the wallet.
Total cost of the wallet = Cost price of the wallet + sales tax
⇒ Total cost = 31.95 + 7.5% of 31.95
⇒ Total cost = 31.95 + 0.075 × 31.95
⇒ Total cost = 31.95 + 2.40
⇒ Total cost = $34.35
Hence, The total cost of the wallet = $34.35
