Answer:
2. $23.64
3. 4%
Step-by-step explanation:
2.
The relationship between selling price, tax, and final purchase price is ...
selling price × tax rate = tax
selling price + tax = final purchase price
For this problem, we have ...
tax = $22.00 × 0.062 = $1.36
final purchase price = $22.00 +1.36 = $23.36
__
3.
Using the above relations, we find ...
tax = final purchase price - selling price
tax = $8.32 -8.00 = $0.32
tax rate = tax/selling price
tax rate = $0.32/$8.00 = 0.04 = 4%
