3 packets of French fries, 2 cheeseburgers, and one drink cost $10.95. 1 packet of French fries, 2 cheeseburgers, and 3 drinks cost $11.25. Find the price of 1 packet of French fries, 1 cheeseburger, and one drink?

Any help would be great. I got this so far:

3f+2c+1d=10.95
1f+2c+3d=11.25

I subtracted the equations and got:
2f-2d=-.30
f=d-.15

I plugged the f (in terms of d) into an equation above but that doesn't help.

If you add the two equations together - what do you get?

Remember, you need to find (c+f+d).
