While docked, the captain wants to resupply the ship’s missiles and ray-guns. You will need to explain to the captain what information you must know and how that can be used to determine the number of missiles and ray-guns to fill the ship and use all the batteries.
The ship can hold only 15 weapons total and only has 45 batteries.
@phi can you help me create an equation?

The missiles and ray-guns each require different amounts of batteries to operate.

phi · Answer

I would think you need to know how many batteries each type needs.

anonymous · Answer

yeah idk it doesnt give that :/

You will need to explain to the captain what information you must know 
you need to know how many batteries each type needs.

anonymous · Answer

yeah how do i create an equation with that

anonymous · Answer

so the battery can be a unknown variable

phi · Answer

Are you sure they do not give you the number of batteries needed for each type?  

If we don't know we can do this:

let x= # of missiles
y= # of ray guns

a = # of batteries for missiles
b= # of batteries for ray guns

you can say
x+y=15   (number of weapons must add up to 15 to fill the ship)
ax + by ≤ 45  ( the total number of batteries has to be 45 or less)

yeah they dont thank you!
