Question

a music store sells a used guitar for $120. This is $25 more than 1/2 the cost of a new guitar of the same brand. what is the cost of a new guitar?

Answer 1

$190.

Explanation:

We can write the equation 120=25+1/2n where n is the cost of a new guitar. First, we subtract 25 from both sides to get 95=1/2n. Then, we multiply both sides by 2 to get 190=n. Therefore, the cost of a new guitar is $190.
