A cotton candy vendor has 9 blue cones of cotton candy to sell. If the blue cotton candy is 25% of the total number of cones, how many total cotton candy cones does he have?
.25 x = 9
To find the total number of cotton candy cones, you need to divide the number of blue cotton candy cones by the percentage of blue cones.
Let's say x represents the total number of cotton candy cones. We know that 25% of x is equal to 9.
So, we can set up the equation: 0.25x = 9.
To solve for x, divide both sides of the equation by 0.25:
x = 9 / 0.25
Performing the calculation, x equals 36.
Therefore, the cotton candy vendor has a total of 36 cones of cotton candy.
