Find the selling price. Original price of the telescope: $99.99 Discount: 13%

Answers

There is no discount stated but I'm assuming this problem is the same problem I encountered before.

Original price of the telescope is $99.99
Discount: 13%

$99.99 * 13% = 12.9987 or 13
$99.99 - 13 = $86.99 or $87

New selling price is $86.99 rounded up to the nearest unit $87.00

Original price = $99.99

Since there is 13% discount. New price = 100% - 13% = 87% of Original price.

= 87% of 99.99

= 0.87 * 99.99

≈ 86.99

Selling price ≈ $86.99
