So you would subtract 0.32 from 1.16 because it is the initial amount. Then divide what you get from that (0.84) by .21. You're gonna get .04- but that's not the answer because you have to add the initial ounce that is worth $0.32. So The answer is B
The answer would be B because you would first subtract 0.32 from 1.16 so that would equal to one ounce and for the remaining of 1.16 you would divide or subtract by 0.21
