Here are the potential answers...
- 00:36
So this question is a two-parter.
- 00:38
First we have to calculate the new sales price -- 35% off.
- 00:42
Old price: $80.
- 00:44
Discount: 35% of the old price which is... .35 times 80... or 28.

Realdeal25 gets excited when he sees that he finally has an order request...
