# How do you calculate discounts?

I want to take 30% off \$40.

how do you calculate it and what is the answer?

easiest way is to just multiply them together. Remember that 30% can also be written as .3.

Now, 40 * .3 = 12.

take 12 away from 40.

What's the question? Cost? or discount?

Cost is \$28. discount is \$12.

#1

x = (0.3)*(\$40)

x = \$12

You would end up paying \$40 - \$12 = \$28

#2

say

\$40 = 100%

\$ x = 30%

do the math

x = (30* 40)/100 = \$12

#3

40 x .30% is the same as 40 x (10% x 3) so think 40 x .10= 4 and 4x3= 12. 40 - 12= 28

#4

As you know,

\$40 = 100%

Take 30% off = left 70%

So

\$40 x 70% = \$28

#5

Multiply ,30 by 40 that's the discount then subtract that from 40 and that's the price. The discount is \$12 so the price is \$28

#6

30% discount means You have \$30 discount in \$100....

So...........

In \$100 you have \$30 discount

In \$1 You have \$(30/100) discount = \$0.3 discount

In \$40 you have \$ (0.3 x 40) discount = \$12 discount

So the price is \$28 and discount is \$12.......

In calculator you can count the discount like this........

40 x 30% = 12.

THANK YOU

40x.3 = 12

so at 30% off the new price is 40 - 12 = 28

whenever you have a percentage like 20% or 50%, the percentage is really a ration of 20/100 or 50/100 so it will be a decimal when you get a calculator out. if the percentage has two digits like 20% it will be .20, and if it has one digit like 5% it will be .05 time whatever the price is then you subtract the percentage off of the original price. sorry if that was a little sloppy. happy thanksgiving
