zzr0ck3r · Answer

we start with 187 gallons, and we are filling at 8g/h
example: so if we fill for 8 seconds we add 8(g/h)*8*h = 64g
then we add that to 187 for our total
so
f(t) = 187 + 8t

ok im lost

zzr0ck3r · Answer

imagine you had 20 bucks
and I gave you another 5 bucks an hour
then the function would be
f(x) = 20+5t
does this makes sense?

zzr0ck3r · Answer

just like that you answer is
f(x) = 187 + 8t
