Sophie buys a couch for $864.00 after a 20% discount. What is the regular price?

$1080

Step-by-step explanation:

If it was 20% off, that means it was 1/5 off because 20% as a fraction is 1/5. Next, if it was 1/5 off that means that $864 represents 4/5 of the price. You can think of it like an equation, where .

To solve this equation, you would first get rid of the fraction by multiplying both sides by 5:

Next divide both sides of the equation by 4 to solve for x:

The regular price is $1080

You can also check this by doing 4/5 of 1080 = 864

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
