The question is asking us to multiply three numbers and then to round the result to the nearest hundredth. First we will calculate: 7.2 * 12 * 0.23 = 19.872. Now we have to round it to 2 decimal places. If we had 19.875 as a result we would round it to 19.88. But we have 19.872 ( 2 is smaller than 5 ) and we will round it to 19.87. Answer: C ) 19.87.
