Answer:
$190.
Step-by-step 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.
1,3 when you rotate 180 you just change the signs
