The bakery manager at the grocery store decides to have a 18% off sale on all bread. You decide to purchase 5 loaves of bread. Let b be the original price of a loaf of bread. Expand the expression 5(b-0.18b). What do the terms of the expansion represent?
The expression 5(b-0.18b) represents the expanded form of the expression for the total cost of 5 loaves of bread after the 18% discount.
Expanding the expression, we get:
5(b-0.18b) = 5b - 5(0.18b) = 5b - 0.9b
The terms of the expansion represent the following:
- The term 5b represents the original price of a loaf of bread without the discount, multiplied by the quantity of 5 loaves.
- The term -0.9b represents the amount of discount applied to each loaf of bread (18% of the original price), multiplied by the quantity of 5 loaves.
