Ellipsis in sentence; 'number' or 'numbers'

Hi,

For the following sentence,

The goal is to increase the number of sponsored medical kits and the number of sponsored tents by 20%. (2 distinct numbers)

Should it be shorten to:

The goal is to increase the number of sponsored medical kits and tents by 20%

Or,

The goal is to increase the numbers of sponsored medical kits and tents by 20%

Thanks.
