An adult elephant drinks about 225 liters of water each day. Is the number of days the water supply lasts proportional to the number of liters of water the elephant drinks?

this is a proportional relationship, since on "day 0" (before the first day passes) the elephant drinks 0 liters, and drinks the same amount of water each day

How do you show work?

vocaloid · Answer

um, I guess you could try writing an equation like

amount of water = 225*number of days

vocaloid · Answer

to show that the relationship is proportional
