Problema Solution
After a 20% reduction, the price of the computer was $800. What was the original price of the computer before the reduction?
Answer provided by our tutors
let x = the original price of the computer before the reduction
After the 20% reduction the new price is: x - 0.20x = x(1 - 0.20) = x*0.80
0.80x = 800 divide both sides by 0.80
x = 800/0.80
x = $1,000
the original price of the computer before the reduction was $1,000.
