If the average of 10% of a number, 25% of that number, 50% of that number, and 75% of that number is 24, what is the number? Where x is the unknown number...10% x + 25% (10% x) + 50% (25% x 10% x) + 75% (50% x 25% x 10% x)/4. The word of means multiplication. There are four values (10%, 25%, 50%, and 75%), so to get the average, divide by 4.
What are some real-world examples of the formula? Recipes. DIY's. If you got directions like that, you would call the customer service rep to complain, huh? Can you think of better examples?

(.10x + .25x + .50x + .75x)/ 4 = 24
