of the total amount that jill spent on a shopping trip , excluding taxes , she spent 60 percent on clothing , 20 percent on food , and 20 percent on other items . if jill paid a 10 percent tax on the clothing , no tax on the food , and an 10 percent tax on all other items , then the total tax that she paid was what percent of the total amount that she spent , excluding taxes ?
"assume she has $ 200 to spend . tax clothing = 60 % = $ 120 = $ 12.00 food = 20 % = $ 40 = $ 0.00 items = 20 % = $ 40 = $ 8.00 total tax = $ 20.00 % of total amount = 20 / 200 * 100 = 10 % answer a"
multiply(divide(add(multiply(60, divide(10, const_100)), multiply(20, divide(10, const_100))), const_100), const_100)
