Sannan ka tantance adadin kwalban kwalba da Marla za ta iya ajiyewa kowace rana ta hanyar rage adadin da ta kashe daga adadin da ta samu: 20 kwalban kwalba / rana - 4 kwalban kwalba / rana = 16 kwalban kwalba / rana. A ƙarshe, raba adadin kwalban kwalban da Marla ke buƙata da adadin da take adanawa kowace rana: kwalban kwalba 384 / kwalban kwalba 16 / rana = kwanaki 24. Saboda haka, amsar ita ce 24. <eng> First find how many lizards you get for one gallon of water: 3 lizards / 5 gallons = .6 lizards / gallon. Then figure out how many lizards 80 gallons of water is worth: 80 gallons * .6 lizards / gallon = 48 lizards. Then figure out how many bottle caps 48 lizards is worth: 48 lizards * 8 bottle caps / lizard = 384 bottle caps. Then figure out how many bottle caps Marla can save each day by subtracting the number she spends from the number she finds: 20 bottlecaps / day - 4 bottlecaps / day = 16 bottlecaps / day. Finally, divide the number of bottle caps Marla needs by the number she saves each day: 384 bottle caps / 16 bottle caps / day = 24 days.
Thus, the answer is 24.
