Exercise 15 Page 276

We want to find the sale price or selling price. Let's consider the given information! &Original price:$15 &Discount:5 % &Sale price:? In order to find the sale price, we need to subtract the discount in dollars from the original price. Original price- Discount= New priceFirst, we have to find the cost subtracted by the discount, which is 5 % of $15. We can find the value of the discount by multiplying the original price by the discount rate.
$15* 5 %
$15* 0.05
$0.75
Finally, by subtracting $0.75 from $15, we get the new price including the discount. $15- $0.75= $ 14.25
