The total cost of a purchase including sales tax of 6% can be calculated by the expression
1.06 (p) where p is the pre-tax purchase. What is the total cost of a purchase if the pre-tax purchase is $25.00?
The total cost of the purchase would be 1.06 * $25.00 = $26.50.
To calculate the total cost of a purchase including sales tax, you can use the expression 1.06(p), where p is the pre-tax purchase.
Given that the pre-tax purchase is $25.00, we can substitute this value into the expression:
1.06 * $25.00 = $26.50
Therefore, the total cost of the purchase, including sales tax of 6%, would be $26.50.
To get the total cost of a purchase including sales tax, you can follow these steps:
1. Identify the sales tax rate as a decimal. In this case, the sales tax rate is 6%, which can be represented as 0.06.
2. Multiply the pre-tax purchase by the sales tax rate. In this case, the pre-tax purchase is $25.00, so you would multiply $25.00 by 0.06.
$25.00 * 0.06 = $1.50
3. Add the result from step 2 to the pre-tax purchase to calculate the total cost, including sales tax.
$25.00 + $1.50 = $26.50
Therefore, the total cost of the purchase, including sales tax, is $26.50.
