A florist designs two high profit arrangement a funeral wreath and a bridal centerpiece. The company'[s employees can complete up to 17 arrangements each day using up to 26 total person hours of labor. It takes 4 person hours to complete 1 funeral wreath and 1 person hour to complete 1 bridal centerpiece. How many of each type of arrangements should the florist produce daily for maximum profit, if the profit on a funeral wreath is $65 and the profit on a bridal centerpiece is $42?

To maximise profit we need to do

 Max( 65x + 42y)

Where x = Funeral Wreath ( FW)

y = Bridal Centerpiece ( CP )

x + y <= 17 such that we maximise the profit.

Now we have a few options to add on to the total man hours that is 26.

FW = 4 person hour , CP = 1 person hour

So, FW will be in multiple of 4 and CP in multiple of 1. 

We check how many combinations are possible.

Option 1:Person Hour.... FW = 24 CP= 2.............Total numbers made x = 6 y = 2

Option 2:Person Hour....  FW = 20 CP = 4.............Total numbers made x = 5 y= 4

Option 3:Person Hour....  FW = 16 CP = 10.............Total numbers made x = 4 y = 10

Option 4:Person Hour....  FW = 12 CP = 14.............Total numbers made x = 3 y = 14

Option 5:Person Hour....  FW = 8 CP = 18.............Total numbers made x = 2 y = 18

Option 6:Person Hour....  FW = 4 CP = 22.............Total numbers made x = 1 y = 22

Option 7:Person Hour....  FW = 0 CP = 26...............Total numbers made x = 0 y = 26

 But we know, sum of x and y should not exceed 17, hence Option 5 to Option 8th are ruled out.

Clearly, now we see which option maximises profit. By putting values of x and y for Max( 65x + 42y)

Option 1: Max( 65x + 42y) = Max ( 65 * 6 + 42 * 2 ) = 474

Similarly calculating for all options we will get that for x = 3 and y = 14 the value of profit maximises.
