Best ResponseYou've already chosen the best response.0@ANA789 It doesn't say to round it up but I don't have an answer choice that has a decimal at all

Best ResponseYou've already chosen the best response.0Your answer is going to be 50 units because when you round up 20.51, it goes to 21, therefore 21+14+15=50 units
