How do I use percent [%]?

Question

Like, say you were looking at something costing $7,500 and a guy says that the price will go up by 20% tomorrow. How do I do this?

Answer 1

7 500 x 20 % = 7 500 x 20/100 = 7 500 x 0.20 = 1 500

this means that price is going up by $ 1 500 tomorrow

so

you will pay 7 500 plus 1 500 which means you pay  $ 9 000

Answer 2

20%=0.20

7,500(0.20)=1,500

7500=1500=$9000

Answer 3

convert it into a fraction

20% is a fifth

then divide 7500 by 5 and mulitply by 6 as you are adding on a fifth

Answer 4

20% = 0.20 (divide % by 100)

Multiple 0.20 * $7500 = $1500 is the increase so the new price is $9000

Answer 5

do 1.20 * 7500 =

or find 20 % of 7500 and add it onto the original price.

= 0.2 * 7500 =

or 10% = 750. therefore 20% = 2*750 = 1500

then add it on
