Spiral Review: You may use a calculator. 15) A toy store is having a sale. A video game system has an original price of \( \$ 99 \). It is on sale for \( 40 \% \) off the original price. Find the sale price of the game system. Round to the nearest cent.

To calculate the sale price, first determine the discount amount. A \( 40\% \) discount on the original price of \( \$ 99 \) means you calculate \( 0.40 \times 99 = \$ 39.60 \). Next, subtract the discount from the original price: \( 99 - 39.60 = \$ 59.40 \). Therefore, the sale price of the game system is \( \$ 59.40 \), rounded to the nearest cent. Now, here’s a tip: Always check your math by recalculating the discount and confirming the final price. A common mistake is to miscalculate percentages directly in your mind, so writing it down or using a calculator can save you time and frustration.
