This is a problem using proportions.

a/b = c/d where: ad = bc

1/4 : 5 = x : 8

a = 1/4 ; b = 5 ; c = x ; d = 8

get the cross products: ad = bc

1/4 * 8 = 5 * x
8/4 = 5x
2 = 5x
2/5 = x

2/5 of a pizza can be purchased for 8 dollars.

to check:

1/4 : 5 = 2/5 : 8

1/4 * 8 = 5 * 2/5
8/4 = 10/5
2 = 2

Find the sale pice is the original price is $82 and discount is 10%

Tpy6a [65]

First you should find the discount so you can say:
10/100 = ?/82
so ? is your discount and ? is equal to:
? = 82*10/100 = 8.2
so your discount is $8.2 and your sale price will be:
$82 - $8.2 = $73.8 :)))
I hope this is helpful
