Question

A) $102.92
B) $112.92
C) $104.00
D) $113.00

Answer 1

To find the total cost of the scooter, we add the assembly fee to the base price, calculate the sales tax, and then add the tax to the subtotal. After rounding to the nearest cent, the total is $114.45. However, among the provided options, $113.00 is the closest, suggesting an error in the provided choices or calculation.

Step-by-step explanation:

To determine the total cost of a scooter that costs $80 plus a $25 assembly fee and has a 9% sales tax, we need to first add the assembly fee to the base cost of the scooter to find the subtotal, then calculate the sales tax based on that subtotal, and finally add the sales tax to the subtotal to find the total cost.

1. Add the base cost of the scooter and the assembly fee: $80 + $25 = $105 (subtotal).
2. Convert the sales tax rate from a percentage to a decimal by dividing by 100: 9% / 100 = 0.09.
3. Multiply the subtotal by the sales tax rate to find the amount of sales tax: $105 × 0.09 = $9.45 in sales tax.
4. Add the sales tax to the subtotal to get the total cost: $105 + $9.45 = $114.45.

After rounding to the nearest cent, the total cost of the scooter including tax is $114.45. However, this total is not one of the options provided, suggesting a possible error in the question options or in the calculation. Given the options listed, the closest value to the calculated total would be $113.00 (Option D), assuming it was supposed to be rounded down rather than to the nearest cent as typically done with currency.
