A television sells for $724 where the sales tax rate is 6.25% of the purchase price. What total amount does the buyer pay at the register?
A$769.25
B$779.25
C$45.25
D$724.63
Answer & Solution
Correct answer: A. $769.25
1. First find the sales tax: change 6.25% to a decimal, 0.0625.
2. Multiply: 0.0625 x 724 = 45.25, so the tax is $45.25.
3. The total cost equals the purchase price plus the sales tax.
4. Add: 724 + 45.25 = 769.25, so the buyer pays $769.25.
5. $45.25 alone is only the tax, the answer to a different question than the total asked for here.
