Belks is having a 20% off sale on pajama pants if the sale price is $12.50 what was the original price of the pajama pants
Answered by oobleck
well, 20% off means the sale price is 80% of the original, right?
Answered by henry2,
1. (405/345) * 100% = 117.4%.
% increase = 117.4%-100% = 17.4%.

2. 0.8P = 12.50
