100%-40%=60%

90 cent is 60% of what number?

The trick is to find what the word means in math term. For instance, the word "is" mean equal and the word "of" means to multiply. The sign (*) means to multiply. You can write the equation as 0.90=(is) 0.60*(of) number. 0.90=0.60n

Let n stand for the original price. You would want the n to be alone. So you divide both sides by 0.60. For instance:

0.90=0.60n

0.90/0.60=0.60n/0.60

1.50=n

Therefore, the original price is $1.50.

Lastly, you can check to make sure it is correct.

0.90=0.60*1.50

0.90=0.90

Hopefully, that helps you.

Hooah!

You use n as the unknown of the value of her sales. You can write this equation as

0.02n=50

You would want the n to be alone. So you divide both sides by 0.02.

0.02n/0.02=50/0.02

n=2500

Therefore, the answer is $2500.

Lastly, you can check to make sure it is correct.

0.02(2500)=50

50=50

50 = .02s

s = 50/.02

s = 2500

Check

2500 * .02 = 50

-----------------------------------

90 = p(1 - .40)

90 = .6p

p = 90/.6

p = 150

Original price 150 cents = $1.50

0.02x=50

x= $2500

40% discount means 60% of the original price:

0.6x=0.90

x= 0.6/0.90= $1.50

$50 ÷ .02 = $2,500. The value of her sales was $2,500.

$2,500 * .02 = $50.
