Jennifer went to the post office for stamps. She bought the same number of 8 cents stamps and 10 cents stamps. She also bought as many 2 cents stamps as both of the other two combined. How many of each kind did she get if she paid a total of $4.40 for them all?

Answer 1

(8 * n) + (10 * n) + (2 * 2 n) = 440

solve for n
