How much is one can of biscuits if four cans equal 1.88?

Depends how many biscuits are in the can. Say there are 5 biscuits in a can, you would take $1.88 and divide it by 4 to get the cost of each can. Once you get this cost, $0.47, you would divide this number yet again by the number of biscuits in the can to get the individual cost of each biscuit, $0.09.
