Wani bought a cow for sh 42000 after being offered a 16% discount. How much money would have been the discount had she bought the cow for sh 21000?
so .84x = 42000
x = 50000 <---- selling price
suppose Wani paid 21000, that would have been a discount of 29000
discount rate = 29000/50000 = .58 or 58%
