Lin's father spent $20 on ice cream for the family. He had to pay a 7% sales tax. What was the total cost of the ice cream? $

*Hint: be sure to include 2 decimal places to show the cents*

Answer 1

Answer:

6%→0.06

Now, we need to multiply the pre-tax cost of this item by this value in order to calculate the sales tax cost.

\textup{Sales tax}=0.06\times\$2.35

\textup{Sales tax}=\$0.141

Round to two decimal places since our total is in dollars and cents.

\textup{Sales tax}=\$0.14

Last, add this value to the pre-tax value of the item to find the total cost.

\textup{Total cost}=\textup{Pre-tax value}+\textup{Sales tax}

\textup{Total cost}=\$2.35+\$0.14

\textup{Total cost}=\$2.49

Step-by-step explanation:

Answer 2

20 * 0.07 = 1.40
20 - 1.40 = $18.60
