A substance weighing 961 ounces decays at a rate of 3.2% PER HOUR. What is the weight of the substance after ONE DAY?

Answers

It would be 961 x (1-3.2(24)) and that would be 961(.232)= 222.952

Answer:

222.952 ounces

Step-by-step explanation:

3.2% of 961 = 30.752

Hours in one day = 24 Hours

30.752 x 24 = 738.048
