I am trying to figure out the labor cost per product on 7 products.

The total labor for one month is $6387. The following is how many of each product were made for the month:

A=638

B=67

C=132

D=14

E=75

F=23

G=58

Each product takes a different amount of time to make. If one of all products could be made in one hour then the following % of time would be spent on each product:

A=5%

B=5%

C=40%

D=2.5%

E=30%

F=15%

G=2.5%

Any help would be appreciated!
