Answer:
D. 3 yoga Classes and 19 circuit training classes
Step-by-step explanation:
Let's look for the hours he wanted, which is 25 hrs,any exceeding digit (n>25) is incorrect, so why D?
WE DETERMINED THAT YOGA CLASS TOOK ABOUT 1HR & 30 MINS WHICH IS 90 MINS IN TOTAL, SO:
90 x 3 classes = 270 mins = 4hrs and 30 mins
WE DETERMINED THAT CIRCUIT TRAINING CLASS TOOK ABOUT ONLY ONE HOUR WHICH IS 60 MINS IN TOTAL, SO:
60 x 19 classes = 1140 mins = 19 hrs
HAVE A WONDERFUL DAY
