A sign says that the price marked on all music equipment is 30% off the original price. You buy an electric guitar for the sale price of $315 how much money did you save off the original price of the guitar

You saved $135 off of the original price of the guitar

Step-by-step explanation:

The original price of the guitar is $450. If we subtract 30% of the original price, we will essentially be solving 450 - 135 which gives us $315. Since we know that 30% was the amount taken off, 30% of the original price is how much you saved. So, you saved $135 off of the original price of the guitar.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
