I’m on vacation! (Can you tell?) So this week’s schedule is way off. But when I saw that Lee Doyle, owner of BTO Self Serve Yogurt in Colorado had sent along her Math at Work Monday responses, I decided to spend just a few moments during a delicious hotel breakfast of Cheerios and milk to post the interview. Then I’m back in the car, headed to Cincinnati to my cousin’s wedding.

There’s nothing better than a cool treat on a hot summer’s day, and since I was a little girl, the options have expanded exponentially. From popcicles to snowballs (a Maryland-only experience) to frozen yogurt — ice cream isn’t the only sweet, cold treat available. At the Doyle’s Highland Ranch location of BTO Self Serve Yogurt, you can create your own delicious treat. But first, the math:

Can you explain what you do for a living? 

I am responsible for creating and making all the yogurt at the shop, buying ingredients for recipes and estimating useage of product and toppings weekly.

When do you use basic math in your job?

I use math all day, everyday. Since I create and follow recipes, I use addition, subtraction, liquid and dry measurements, fractions, estimation, equivalency charts multiplication, division, just about every kind of basic math you can think of. For example, if I am creating a new recipe, I use one cup of our basic yogurt and add a teaspoon or tablespoon of various flavors to come up with a new flavor I like. Then I have to write a recipe using a gallon of basic yogurt, because all our recipes are based on one fluid gallon.

Do you use any technology to help with this math?

When I shop for ingredients, I use a calculator constantly to determine price per ounce to be sure the ingredients are within our pricing guidelines.

How comfortable with math do you feel?

I always liked math and feel very comfortable using it. In high school, I took algebra, trigonometry and solids but did not take calculus.

Do you have questions for Lee and Jack? Ask them in the comments section. And of course stay cool with a sweet treat, like frozen yogurt.
