Hey,

Solution,

Markedprice(MP)=$80

Discount percent=20%

Now,

Discountamount=discountpercentofMP

=20%of80

=20/100*80

=$16

Again,

Sellingprice(SP)=MP-Discount amount

=$80-$16

=$64

So,thesalepriceoftheCDplayeris$64.

Answer 2

Answer: If the CD player sells regularly for $80 but is on sale for 20% off the sales price will now be $64. The equation used is ? x 0.8 = 20%. Think of teams of 10. 8+2 = 10 right? Now put transfer that to hundreds 80+20 = 100 or in this case 1 whole number. To get a certain percent off you need to x it by 0. (Other part of teams of 10) so if it was 63% off you would do ? x 0.37. If you want to keep it simple though just times the original number, in this case 80, by 0. And then the percentage ( 80 x 0.60 ) that’ll give you how much to take off of $80 to reach 20% off.

Jessie is building a doghouse. For one side of the roof, she needs a board that is 7 3/4 feet long. She has a board that measure 9 1/12 feet. How much of the length does she need to cut from the board? Show your work and simply the fraction.

Answers

9 1/12 ft = 109/12
7 3/4 = 31/4
You need to give them the same denominator, so you'll need to multiply the top and bottom of 31/4 by three
109/12 - ((31*3)/(4*3))=x
109/12 - 93/12 = x
(109-93)/12 = x
16/12 = x
(16/4)/(12/4) = x
4/3 = x
4/3 = 1 1/3
Jessie needs to cut 1 1/3 feet off the board.
