On opening day a new music store a 40% discount on all electronic guitars. If the regular price on a guitar is $425 , what is the sales price?

Answer 1

If you multiply .4(425) you will have the amount of the 40% discount.

If you subtract that amount from the original price you will have the sale price:

425 - .4(425)

You can do that calculation to get the sales price, but take note of the following.

Each term above contains the factor 425. Try picturing factoring out the 425:

425[1 - 0.4]

425(0.6)

Another way to think about it: if you take 40% off there will be 60% left.
