3 investors , a , b , and c , divide the profits from a business enterprise in the ratio of 5 : 7 : 8 , respectively . if investor a earned $ 2500 , how much money did investors b and c earn in total ?
let profit for a = 5 x profit for b = 7 x profit for c = 8 x investor a earned = 2500 5 x = 2500 = > x = 500 total profit for b and c = 7 x + 8 x = 15 x therefore , 15 x = 15 * 500 = 7,500 answer c
add(divide(divide(add(multiply(divide(7, add(add(5, 7), 8)), divide(2500, divide(5, add(add(5, 7), 8)))), multiply(divide(8, add(add(5, 7), 8)), divide(2500, divide(5, add(add(5, 7), 8))))), const_1000), const_2), const_0_25)
