There is something missing. Can you supply the question exactly as written?

If ‘r’ is the number of pens, then the total cost is 0.30r (30 cents x r). If you have the final cost and the unit price, then you can figure out how many pens there are.

For example:

Suppose that the total price is $4.50. If pens cost 30 cents ($0.30), then how many pens are there?

Answer:

Let r be the number of pens

0.30r = 4.50

r=4.50/0.30

r=15

There are 15 pens.
