Answer 1

Iris wants to buy two necklaces, one for her sister and one for herself. The necklace for her sister costs $42.00, and the necklace for herself costs $28.00. The sales tax on the purchases is 8%.

A. Show your setup and work, as well as your answer.

B. Explain what process you used to find the answer.

Answer 2

\[$42+$28 = $70\]

So we now know she spent $70 without tax.
\[$70*.08 =$5.60\]
The sales tax was $5.60

To find the total cost you just add the sales tax to the cost of the necklaces.

So, $70 + $5.60 = ?
