Answer:
105 minutes
Step-by-step explanation:
we know that
Michael can type 4 pages of his term paper in 30 minutes
so
using proportion
Find out how long will it take him to type the paper if it has 14 pages

Let c=the number of batches for the cookies; b=that for the brownies.
If $P=the profit, then
maximize P=5c+4.5b, subject to the constaints:
3c+4b<=100 (cost)
2c+b<=45 (time)
b,c >=0
The simplest way to find the suitable b & c is
to solve
3c+4b=100
2c+b=45
for b & c
The result is b=13 & c=16
=>
max. p=5(16)+4.5(13)=$138.5
Hope this helps :)
