Below is a spreadsheet we were given and have to find the solution using solver, i understand how to use solver but am confused with the constraints below are the constraints tables and wandering if anyone can help me understand what each means!

Product min con min

x1 0 >= 0

x2 0 >= 4

x3 0 >= 3

x4 0 >= 0

x5 0 >= 3

x6 0 >= 0

x7 0 >= 2

x8 0 >= 0

x9 0 >= 3

x10 0 >= 3

Product max con max

x1 0 <= 40

x2 0 <= 30

x3 0 <= 15

x4 0 <= 18

x5 0 <= 25

x6 0 <= 30

x7 0 <= 32

x8 0 <= 20

x9 0 <= 20

x10 0 <= 18

I think the maximum i understand it the minimum that im getting confused with any help would be appreciated
