Answer: 105.70$
Explanation:
Nelly bought a shredder for 39.99$, a laminator for 31.65$, an electric pencil sharpener for 15.99$, and a magnetic credit card reader for 14.99$; the sales tax is also 3 percent. What you want to do first is add all the prices together. After adding, you should get 102.62$. Then because of the 3% tax rate, you would have to add 3.08$ to the total amount, which comes out to be 105.70$
