During a 30% off sale, lourdes pays $140 for a swing set. what was the original price of the swing set?

To figure this out I took 0.30 which is the decimal form of 30% and multiplied it by 140 to get $42, which i added to the 140 because it is the missing 30%. After adding the missing 30% you shouldve gotten $182 as the original price.

Dis the correct answer
