<PRE><B>Question 214819</B>
Five pens of the same type cost the same as two notebooks of the same type. If one pen and two notebooks cost $4.20, what is the cost of one pen?
-------------------
Value Equation:: 5p - 2n = 0
Value Equation:::: p + 2n = 420 cents
-----
Add the two equations to get:
6p = 420
p = 70 cents (cost of one pen)
