If we assume the number of polo shirts have been sold is x, the number of casual shirts have been sold will be 4x.
x*18+4x*9=$1080
(18+36)x=$1080
54x=$1080
x=20
The number of casual shirts have been sold is 4*20=80

X is N(270, 16)

X>302 means

P(Z>2) = 0.25
Thus 25% of days will the company have to hire extra help or pay overtime
