Blake has 9 times as many nickels as Corey. If Corey had 80 more nickels, the two boys would have exactly the same amount. How many nickels does Blake have?

what is if corey had 9 nickels and 8 dimes whats the anserw

If Corey has x nickels, then

9x = x+80
Now finish it off

To find out how many nickels Blake has, let's first set up some equations based on the given information:

Let's assume Corey has 'x' nickels.
Blake has 9 times as many nickels as Corey, so he has 9x nickels.

If Corey had 80 more nickels, the two boys would have exactly the same amount. This means that if Corey had x + 80 nickels, Blake would still have 9x nickels.

Now we can set up an equation:
9x = x + 80

To solve for x, we start by simplifying the equation:
8x = 80

Next, we divide both sides of the equation by 8 to solve for x:
x = 10

So Corey has 10 nickels.

To find out how many nickels Blake has, we substitute the value of x back into our previous knowledge that Blake has 9 times as many nickels as Corey:
Blake has 9 * 10 = 90 nickels.

Therefore, Blake has 90 nickels.
