Question

 will buy magnets for $2.00 each and they come in a set of 4.  How much if I brought 12 sets

Answer 1

First figure out how much one set costs. If a set consists of 4 magnets and each magnet is $2.00, then we have to multiply 4x2=$8.00 for one set. Now you can figure out how much 12 sets will cost by multiplying again.
