Question

> Un grupo de amigos pide en una cafetería 4 refrescos y 3 bocadi- llos. La cuenta total ha sido de 9,25 € y sabemos que un bocadillo cuesta 0,75 € más que un refresco. ¿Cuánto cuesta cada bocadillo y cada refresco? ​

Answer 1

Answer: Let's denote the cost of a soda as "x" and the cost of a sandwich as "x + 0.75".

Given that the group ordered 4 sodas and 3 sandwiches, we can set up the following equation based on the total cost:

4x + 3(x + 0.75) = 9.25

Solving for x:

4x + 3x + 2.25 = 9.25

7x + 2.25 = 9.25

7x = 9.25 - 2.25

7x = 7

x = 1

So, the cost of a soda (refresco) is 1 euro, and the cost of a sandwich (bocadillo) is 1.75 euros.
