last week john spent 30 percent of his wages on recreation . this week , his wages are 25 percent less than last week ʼ s wages and he spent 20 percent of his wages on recreation . the amount he spends on recreation this week is what percent of the amount he spent on recreation last week ?
say john ' s wages last week were $ 100 , so he spent 0.30 * 100 = $ 30 on recreation ; this week ' s wages is 0.75 * 100 = $ 75 , so he spends 0.2 * 75 = $ 15 on recreation ; 15 / 30 = 0.50 , hence the amount he spends on recreation this week is 50 % of the amount he spent on recreation last week : 30 * 0.5 = 15 answer : e
multiply(divide(multiply(divide(20, const_100), multiply(divide(subtract(const_100, 25), const_100), const_100)), multiply(divide(30, const_100), const_100)), const_100)
