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

Alexxandr [17]

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

$Cost = \$120 - \$30$

$Cost = \$90$
