5b - 0.9b is the equivalent expression and the distributive property is used.

Step-by-step explanation:

The price of bread is marked down 18%. She purchases 5 loaves of bread. We need to rewrite the above expression.

The expression that is used to find the price of 5 loaves of bread is 5(b-0.18b).

We can use the distributive property to solve it as follows:

a(b+c) = ab + ac

Here, a = 5, b = b and c = -0.18b

5(b-0.18b) = 5(b) + 5(-0.18b)

= 5b - 0.9b

So, the equivalent expression is 5b - 0.9b. The distributive property was used to rewrite the expression.

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
