Tony bought headphones that were marked $70. He used a coupon for 15% off, and he paid 6% tax on the discounted amount. What was the final cost of the headphones?

$63.07

Step-by-step explanation:

So we need to find 15% of 70:

0.15*70=10.5

Next we need to subtract 10.5 from 70(since he used a coupon and got it for a lower price)

70-10.5=59.5

After that we need to find 6% of 59.5

0.06*59.5=3.57

Finally we need to add 3.57 to 59.5 since he had to pay extra(due to tax)

3.57+59.5=63.07

Hope this helps!
