a salesperson received a commission of 3 percent of the sale price for each of the first 100 machines that she sold and 4 percent of the sale price for each machine that she sold after the first 100 . if the sale price of each machine was $ 10,000 and the salesperson received a $ 42,000 commission , how many machines did she sell ?
first 100 machines = 3 % commission = 0.03 * 100 * 10000 = 30000 commission from sale of next machines = 42000 - 30000 = 12000 so 30 more machines . . total = 130 machines imo c . . .
add(100, divide(subtract(multiply(multiply(multiply(add(const_4, const_3), multiply(const_3, const_2)), const_100), multiply(add(const_4, const_1), const_2)), multiply(multiply(multiply(const_100, const_100), divide(3, const_100)), 100)), multiply(multiply(const_100, const_100), divide(4, const_100))))
