Question

Jill purchases 3 items valued at $15.00, $23.00, and $45.50. What is the total cost with sales tax if tax is 7%?

a) $84.45
b) $86.34
c) $92.36
d) $95.84

Answer 1

To find the total cost with sales tax, we add the prices of the items to get the subtotal and then calculate 7% of this as sales tax. The final total cost, including the sales tax, should be $89.35, which does not match any of the provided options.

Step-by-step explanation:

Calculating the total cost of Jill's items with sales tax involves two main steps: summing up the cost of the items and then calculating the sales tax based on the subtotal. To start, we first add the costs of the individual items: $15.00 + $23.00 + $45.50, which gives us a subtotal of $83.50. Next, we find the sales tax by converting the tax rate from a percentage to a decimal (7% becomes 0.07) and then multiplying this by the subtotal.

To calculate the sales tax: $83.50 × 0.07 = $5.845. We round this to the nearest cent, which gives us $5.85. Finally, we add the sales tax to the subtotal to find the total cost: $83.50 + $5.85 = $89.35.

It appears there has been an error in the options provided as none match our calculated total of $89.35 (which is not presented in the multiple-choice answers).
