Problema Solution
Tracy buys a songbook and signs up for piano lessons. Her total for the lesson and book is $48. The lesson cost 5 times as much as the songbook. How much does each item cost?

Let 'l' and 's' stand for the respective prices of the lesson and the songbook. We can write:
l+s=48
l=5s
Using Algebrator to solve for 'l' and 's', we get:
l=$40
s=$8
