Question

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?

Answer 1

x = $120 - ($120 / 4)

Answer 2

`\$120(0.75)`

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
`\$120-0.25(\$120)`. 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:

`\$120-0.25(\$120)`

`\$120(1-0.25)`

`\$120(0.75)`

Therefore, another expression would be
`\$120(0.75)`.
