You can make 11 batches of brownies. Divide 8.5 (8 1/2) by .75(3/4)
Answer:
Radius of the convergence is R =
and,
The Interval of convergence is
Step-by-step explanation:
Given function : Σ(21x)^k
Now,
Using the ratio test, we have
R =
or
R =
or
R =
now,
for convergence R|x| < 1
Therefore,
< 1
or
and,
Radius of the convergence is R =
and,
The Interval of convergence is
20.50 * 0.8 = $16.40
16.40 * 0.4 = $6.56
Final selling price = $6.56
