Each cookie costs 2$.
We can find how much each cookie costs by setting up an equation with x being the amount of cookies, and solve
12x=24 12 cookies equals 24 dollars
x=2 By simplifying and dividing both sides of the equation by 12, we get the variable on its own.

Answer:
Aiden and his sister have 360 quarters together. If Aiden has twice as much as his sister, he has 180 quarters.
360/2 = 180
Aiden divides his quarters into 3 equal piles.
180/3 = 60
Aiden has 60 quarters in each of his 3 piles.
-- Ben walks at a rate of 3 miles per hour. If he walks for 'W' hours,
then the distance he covers in that time is 3W miles.
-- Ben runs at a rate of 6 miles per hour. If he runs for 'R' hours,
then the distance he covers in that time is 6R miles.
If he does some running and some walking during the week, then
we might not know how many hours he walked and how many hours
he ran, but we can be sure that the total distance he covered is
<em>Total D = 3W + 6R </em>.
-- If the total distance is 210 miles,and he ran for 25 hours, then
210 = 3W + 6(25)
210 = 3W + 150
Subtract 150 from each side: 60 = 3W
Divide each side by 3 : <em>20 = W</em>
<em>He walked for 20 hours</em> during the week.
<u>Check:</u>
Running hours: R=25, Running D = 6R = 150 miles.
Walking hours: W = 20, Walking D = 3W = 60 miles.
Total distance = 150 miles + 60 miles = <em>210 miles</em> yay !
