Math word problem

Question

There are 5 stacks of 100 paper packages on a truck. There are 60 pieces of paper left in one package. How many pieces of paper are there?

Answer 1

5 stacks x (100/stack) = 500 paper packages

1 package - x pages = 60

So, 500 paper packages x (unknown number of pages/package) + 60 = the answer

If 100 pages per package, then, 50000 + 60 = 50060
