Lyra bought a pair of shoes at a 20% discount.  If she paid $480, how much was the original price of the pair of shoes?
Лира як ҷуфт пойафзолро бо 20% тахфиф харидааст. Агар ӯ $480 пардохт кардааст, нархи аслии ҷуфти пойафзол чанд буд?
How much did Lyra pay? ** Lyra only paid $480 for the pair of shoes which is only 100% - 20% = 80% of the original price.
Define a variable ** So let x be the original price.
Write an equation ** Then 0.8x = $480
Simplify ** Thus x = $480 / 0.8 = $<<480/0.8=600>>600
