Question

find the original price of a pair of shoes if the sale price is $11 after a 75% discount

Answer 1

11$ = 75% of x

75% can be represented as 75/100 = 0.75

algebraically:

11 = 0.75x

solve for x

Answer 2

i have no idea

Answer 3

divide both sides by 0.75
\[11 = 0.75x\]\[\frac{ 11 }{ 0.75 } = x\]you'll need a calculator for this

Answer 4

not NEED absolutely but it's much faster :P

Answer 5

11/0.25 = $44
