Samantha, cleo, and elena had $780 altogether. samantha had $40 more than cleo, and cleo had twice as much money as elena. how much money did cleo have?

$296

Step-by-step explanation:

To solve this we can create an equation in which we will solve for X.  Because according to the question Elena had the least amount of money we will make her X and everything else is based of her amount of money. Cleo had twice as much as Elena making him 2X and Samantha and 40 more than Cleo making her 2X+40.  Because the total is 780 our equation will be

X+2X+2X+40=780 we can combine like terms to get 5X+40=780 then isolate the variable 5X=740 and divide both sides by 5 to get what X is 740/5=148 so Elena had $148 and because Cleo had twice as much as Elena we need to fine 2X which is 2 times 148 which is $296

I hope this helps and if there is any confusion or things that are still unclear just ask I would love to continue to help you figure them out

the discriminant is 64 + 4*1*12 = 112

this is prime.
