1. 24/(63%-59%)= 24/4%= 6,so the phone drop one charge every 6 minutes of listening to top pop.
42/6=7(the percentage consumed in 42 minutes)
46%-7=39%(percentage of battery left)
2. 76%-16%=50%(percentage of battery consumed after watching 3 episodes of "the haunted cave")
80x100%=8.000%(maximum percentage of battery at which the phone can be charged 80 times)
8000%/50=160(episodes of "the haunted cave" the monkey can watch)
3.idk the answer, sorry
