a = adult shirts sold
c = children shirts sold
we know the store sold for every 5 "a", there were 3 "c" sold, so we can say that the adult to children shirts are on a 5 : 3 ratio.
We also know that whatever "c" is, adult shirts sold last weekend was 30 more than that, or namely "c + 30".
Answer:
Diverges
Step-by-step explanation:
For the improper integral to converge the limit must exist, if the limit does not exist or is infinite the integral diverges;
#
Where a and be is infinity
The solution of this is infinity and therefore the integral diverges because the first expression is undefined because ∞/∞, the second term is 4·∞ which is infinity and infinity added to any number is infinity
