Question 380150: if you buy 6 pens and w mechanical pencil you only get $1 change from a $10.00 bill, but if you buy 4 pens and 2 mechanical pencils you only get $2.00 change. How much does each pen and pencil cost? Answer by solver91311(24713) (Show Source):
Well, how many is "w" mechanical pencils? The "w" is below the 2 and the 3 on the keyboard, but if you meant 3, then that would create an inconsistent system. On the other hand, you wrote "mechanical pencil" in the singular, so maybe w = 1.
Let represent the number of pens and let represent the number of pencils.
If w = 1, then:
if w = 2, then:
Solve whichever system actually represents your problem.
