Question

A chair's regular price is $349. It is on clearance for 30% off, and a customer uses a

15% off coupon after that. What is the final cost of the chair before sales tax?​

Answer 1

The final cost of the chair is $207.65 before sales tax.

Explanation:

First, turn 30% into a decimal.

30% --> make the % into a decimal and move it 2 times to the left

This gives you 30% ---> 0.30

Now, multiply.

349×0.30= 104.7

So, 104.7 is 30% of the total price and since it's on clearance, subtract 104.7 from 349.

349-104.7= 244.30

Now, we have to find the price of the 15% coupon.

The coupon says it takes away 15% of, not the original price, but of the price after the clearance is taken away.

So, turn 15% into a decimal.

15% ----> 0.15

Now, multiply 0.15 with 244.30.

244.30×0.15= 36.645

That estimates to 36.65.

Finally, subtract 36.65 from 244.30.

244.30-36.65= 207.65

This gives us the final product of $207.65.
