The sales tax rate is 5%. If Bernie buys a new basketball at $34, what will be the total cost including tax?
julsineya [31]

Answer:

$35.70

Step-by-step explanation:

5% would be 0.05 as a decimal.

multiply 34(0.05):

34(0.05)=1.7

This means that the sales tax would be $1.70.

Next, add $1.70+$34 to find the total cost

$1.70+$34=$35.70

This means that the total cost is $35.70
