Helpp mee!!! I'm really stuck so I need help.
Teresa has three times as much money as Rita. Between them they have €10. How much has Teresa?
Let R = Rita
R + 3R = 10
Sure, I can help you with that!
To find out how much money Teresa has, we can start by assigning a variable. Let's call the amount of money Rita has "x". Since Teresa has three times as much money as Rita, Teresa's amount of money can be represented as "3x".
We know that the total amount of money between them is €10. So, we can write an equation to represent this:
x + 3x = 10
To solve this equation, we can combine the like terms:
4x = 10
Now, to isolate x, we can divide both sides of the equation by 4:
x = 10 / 4
Simplifying, we find:
x = 2.5
So, Rita has €2.50.
Since Teresa has three times as much money as Rita, we can calculate Teresa's amount:
3 * 2.5 = 7.5
Therefore, Teresa has €7.50.
To summarize, Rita has €2.50 and Teresa has €7.50.
