Answer:
Ryan saw 30 ants when he left for spring break.
Step-by-step explanation:
The equation for the number of ants has the following format:

In which P(t) is the population after t days, P(0) is the initial population and r is the growth rate.
Upon returning 17 days later, Ryan counts 3960
This means that
. So


The next day there are 5280 ants.
This means that 
So


From above, we have that

Replacing
