Question

HELP PLZ!!! Michelle owns a clothing store that designs T-shirts and shorts. She sells
the T-shirts for $8 each and the shorts for $15 each. She can work 18 hours
a day at most. It takes her 1 hour to design a T-shirt and 2 hours to design a
pair of shorts. She must design at least 12 items a day, but cannot design
more than 20 items in a day. Which of the values below is the maximum
revenue Michelle can make with these constraints?
A. $164
B. $144
C. $96
D. $138

Answer 1

Answer: B

Step by Step: If it takes 2 hours to design shorts to get $15 and 1 hours to make shirts for $8 you can multiply 8 by 2 and get 16 which is more than 15. The reason you multiply 8 by 2 is because it takes 2 hours to make 1 pair of shorts. With this you then multiply 16 by 9 which gives you 144.

Hope this helps
