Answer:
For #1 the answer is City C
Explanation:
To find the value of anything with a sales tax simply multiply the cost by the tax.
$30 * 2.9%
$30 * .029
$0.87
Now that we have the sales tax, add it to the original cost.
$30 + $0.87 = $30.87
You can do this for each of the sales tax problems. Then compare the answers.
