For a sale a store decreases its prices on all items by 25% an item that cost $120 before the sale now cost $120-0.25 (120) what is another expression for the sale price?

Step-by-step explanation:

We have been given that for a sale a store decreases its prices on all items by 25%. An item that cost $120 before the sale now cost . We are asked to write another expression for the sale price.

Since the store offers an 25% sale offer, this means that cost of an item will be 75% of the original cost as 100%-25%=75%.

We can factor out 120 from our given expression as:

Therefore, another expression would be .

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

nada
