Khloe went shopping for a new video game because of a sale. The store was offering a 10% discount. If the price on the tag was $42, what would be the price after the discount but before tax, to the nearest dollar and cent?
The price after the discount can be found by multiplying the original price by (100% - discount percentage). In this case, the original price is $42 and the discount is 10%, so the price after the discount but before tax is $42 * (100% - 10%) = $42 * 90% = $37.8. To the nearest dollar and cent, the price after the discount but before tax is $37.80.
