## 19015723320 3 years ago A Model NV 300 acoustic- electric guitar I being sold for a list price of 1,899.90 with a cash discount of 3/10, n/30. Sales tax is 7% and shipping is \$30.40. How much is the final price if the cash discount period was met?

I can help you if you tell me what 3/10, n/30 means.

2. 19015723320

Im not sure the problem came that way.

Ah - let's assume it means a 30% discount. You need to be careful about what the percentages apply to. you start with the base amount of 1899.9 then do the discount which I'm guessing is 30%. so 1899.9 *(1-0.3) or 1899.9*0.7 Then you add sales tax. so 1899.9*(1-0.3) *(1+0.07) Then add shipping (assuming it is not taxed) so 1899.9*(1-0.3) *(1+0.07) + 30.40

Then you add sales tax. so 1899.9*(1-0.3) *(1+0.07) Then add shipping (assuming it is not taxed) so 1899.9*(1-0.3) *(1+0.07) + 30.40one second ago •Report Abuse 5 19015723320 0 sorry you lost me one second ago •Report Abuse Delete 3 Rogonic 0 Good Answer Where one second ago •Report Abuse Type your reply ΣEquationDraw Attach File

Adding sales tax is the problem?

8. Rogonic

When you add a percentage amount, you also have the original amount. So if you had something costing 200 then added 7% sales tax it will be the original 200 plus 7% of 200. a quick way to write that is 200 times (1 + 7%) or 200 * 1.07.

9. Rogonic

To increase by a percentage you multiply by 1 + the percentage. To decrease by a percentage you multiply by 1 minus the percentage.

10. Rogonic

Is that what the problem was?

This is all wrong, no no no!. The 3/10, n/10 means 3 cents on the dollar and the seller will give buyers a 3% cash discount if the buyer pays within 10 days. However, it the buyer does not pay within 10 days (n/10~ net/10) the full amount is due in 30 days. She does NOT get a MEDAL!
