Question 296135: Ok I need help with another word problem, these are just confusing to me
Phil is making a Starbuck’s ® run for his exhausted Math 105 classes. He is going to buy a combination of Lattes and Cappuccinos. The Lattes cost $4 each and the Cappuccinos cost $3 each. If he needs 30 drinks total and has $100 to spend, how many of each should he buy?

You can put this solution on YOUR website! L+C=30 L=30-C
4L=3C=100
4(30-C)+3C=100
120-4C+3C=100
-C=-20
C=20
----------------
L+20=30
L=10
-------------
4*10+3*20=100
