This is the equivalent and it has no equal fraction counterpart
The functions are:
and
.
After 2 weeks, under no risk of spiders, the population of the flies is calculated by the function as
.
Similarly, we calculate s(2)=2(2)+5=4+5=9, which means that the spider consumes 9 flies in 2 weeks.
Thus, out of 32 flies, 9 are eaten by the spider, so there are 32-9=23 flies left.
Answer: 23
