Use this mathematic formula to calculate how much candy you should buy for Halloween

“Popular Mechanics” did a story on an overly complicated formula that tells you if you bought enough Halloween candy. The formula is:

T x K x G + D x F x S . . . divided by 75.

“T” stands for the amount of “time” in hours that you plan to hand out candy.
X
“K” is the estimated number of “kids” per hour you expect to show up.
X
“G” stands for “generosity factor” . . . or how many pieces you’ll give each kid.
+
“D” is the number of “days” you’ll have it in your house before Halloween. That’s to factor in all the candy YOU’LL eat.
x
“F” is the number of “family” members in your home, because they’ll eat some too.
x
“S” stands for “sneakiness level,” or the number of pieces your family will eat each day.
Then divide it all by 75, which is the average number of fun size candy bars in a bag.

For example:

Part 1: Gross Candy

• Time: 3 hours
• Kids: 70
• Generosity: 3

Total: 3 x 70 x 3 = 630 pieces of candy

Part 2: Extra Candy Needed Leading Up to Halloween

• Days ahead of Halloween: 6
• Household size: 5
• Sneakiness level: 2

Total: 6 x 5 x 2 = 60 pieces of candy

Part 3: Total Candy Required

630 + 60 = 690 pieces of candy

690 pieces of candy / 75 pieces of candy per bag = 9.2 (round up) = 10 bags of fun-size candy
