A TI-84 graphing calculator costs $98.99.
Find the total cost of the calculator if sales tax is 8%. Round to the nearest cent.
To find the total cost of the calculator with sales tax, you need to add the sales tax to the original price.
Sales tax = (8/100) * $98.99
= $7.9192
Rounding to the nearest cent, the sales tax is $7.92.
Total cost = $98.99 + $7.92
= $<<98.99+7.92=106.91>>106.91
The total cost of the calculator, including sales tax, is $106.91.
To find the total cost of the calculator including sales tax, you need to calculate the sales tax amount and then add it to the original price.
Step 1: Calculate the sales tax amount
Sales Tax = original price × sales tax rate
Sales Tax = $98.99 × 0.08
Sales Tax = $7.92
Step 2: Add the sales tax to the original price
Total Cost = original price + sales tax
Total Cost = $98.99 + $7.92
Total Cost = $106.91
Therefore, the total cost of the calculator, including the 8% sales tax, is $106.91 (rounded to the nearest cent).
