anonymous · Answer

would I multiply 5.5by 100?

anonymous · Answer

We know $A = 100lbs$, so we plug it into $A=5.5t$ to get $100lbs = 5.5t$

Now we just solve for $t$.  Need help for this?

t=18?

yes, I need help....i am unsure

Yes, but to be accurate it is $18.\overline{18}$.  You may want to round up to 19 since on day 18 you are still under 100 lbs.
