Question

For a sale, a store decreases its prices on all items by 25%. An item that costs $120 before the sale now costs $120 - 0,25($120). Use the distributive property to write an equivalent expression for the items cost now

Answer 1

Answer:

$Cost = \ 120 * 1 - \ 120 * 0.25$

Step-by-step explanation:

Given

$Cost = \ 120 - 0.25(\ 120)$

Required

Solve using distributive property

$Cost = \ 120 - 0.25(\ 120)$

$\ 120$ can be rewritten as $1(\ 120)$

So:

$Cost = 1(\ 120) - 0.25(\ 120)$

Factorize:

$Cost = \ 120(1 - 0.25)$

Now, we can apply distributive property on the expression;

$Cost = \ 120 * 1 - \ 120 * 0.25$

Hence, the above is an equivalent expression.

Solving further, we have

$Cost = \ 120 - \ 30$

$Cost = \ 90$
