There are three families in a certain restaurant. The first family bought 2 Spaghetti's, 4 French fries and 6 glasses of Juice and it cost them 110 coins.
The second family bought 3 Spaghetti's, 8 French fries and 3 glasses of Juice and it cost them 155 coins.
The third family bought 5 Spaghetti's, 2 French fries and 10 glasses of Juice and it cost them 170 coins.
My question is, if I will buy a spaghetti, a french fry and a glass of juice, how much would it cost me?
