3 packets of french fries,2 cheese burgers and 1 cup of drinks cost $109.5.
1 packet of french fries, 2 cheese burgers and 3 cups of drinks cost 112.5.
what is the cost of a set?
Ok... I knew there had to be a trick...
If you add the two equations together you get...
4f + 4b + 4c = $222.00
divide both sides of the = by 4 gives....
1f + 1b + 1c = $55.50
All I can say, better be a pretty nice burger fries and a drink for $55.50!!!
This is a systems of equations problem. Harder than I first thought.... normally with 3 unknowns you need 3 equations.... hmmmm.... I'll be back with you.
