You are walking through your town, when you decide that you want to have some coffee (and maybe a sneaky cake). You walk into the coffee shop and ask the server about the cost of the coffee and cake. He looks at you and says, "I will only sell you your desired goods, if you can figure the prices out yourself." He tells you that 2 coffees with one cake would cost you 230 pence. He also tells you that 1 coffee with 5 cakes would cost you 340 pence. Ignoring the effects on the server's employment, how much would 1 coffee cost in pence (you have lost your appetite for cake)?
