Jasmine and Cory had saved up a total of $78. Jasper save six dollars more than twice as much as Corey how much is Corey saved

Let's denote the amount saved by Corey as x.

According to the information given, Jasper saves $6 more than twice as much as Corey. So, Jasper saves 2x + 6.

Now, we know that the total amount saved by Corey and Jasper is $78. Therefore, we can write the equation:

x + 2x + 6 = 78
3x + 6 = 78
3x = 72
x = 24

So, Corey has saved $24.
