 Math Central Quandaries & Queries
 Question from cliff, a parent: a landlord receives $95.00 rent 5% commission was paid to get to$95.00 what was the original number. The answer is obvious but what is the formula. Thanks. Cliff

Hi Cliff,

If the renter pays $R then the commission is 5% of$R which leaves the landlord with 95% of $R. Hence if the landlord receives$L then

0.95 × $R =$L or $R =$L/0.95

In the example you sent $L =$95.00 and hence $R = 95/0.95 =$100.
