Ski Trip Purchase Cost

On a skiing trip, Eve bought two colas for 1 euro and 50 cents each, two muesli bars for 50 cents, and bananas for 2 euros and 50 cents. How much did it cost to buy it in total? How much of the 10 euro bill did they give her back at the cash register?

Final Answer:

x =  6.5 Eur
y =  3.5 Eur

Step-by-step explanation:

$x=2\cdot 1.50+2\cdot 0.50+2+0.50=6.5\text{Eur}$

$y=10-x=10-6.5=3.5\text{Eur}$
