Problema Solution
Erin bought a pair of shoes for 60% off the original price is x, what equation could Erin use to find the original price, p, of the shoes?
Answer provided by our tutors
the price Erin paid was x
60% is written 0.60 as a decimal number (60/100 = 0.60)
the original price was p, where x = p - 0.6p
let 'T' represent the price Erin paid for the pair of shoes, then:
x = p - 0.6p
x = 0.4p
p = x/0.4
so Erin should divide the price paid for the shoes by 0.4 to find the original price of the shoes
