Question: There is 80 mg of caffeine in a cup of coffee. Lisa does not want to drink more than 200 mg of caffeine per day. If she drinks three cups of coffee, how many milligrams of coffee did Lisa drink over her goal?
Answer with step-by-step thinking: Lisa drinks 80 * 3 = 240 mg of caffeine in 3 cups of coffee. She wanted to have 200, so she is 40 mg over her goal because 240 - 200 = 40mg.
So the answer is 40.

Question: The sum of the ages of Jeremy, Sebastian and Sophia in three years is 150. Currently, Sebastian is 4 years older than Jeremy. If Jeremy's age is 40, calculate Sophia's age three years from now?
Answer with step-by-step thinking: The age of Jeremy three years from now will be 40 + 3 = 43 years. Since Sebastian age is four years more than Jeremy's, Sebastian is currently 40 + 4 = 44 years. In three years, Sebastian will be 44 + 3 = 47 years old. The total age of Jeremy and Sebastian in three years will be 47 + 43 = 90. If the total age of Jeremy, Sebastian and Sophia in three years is 150, then Sophia's age in three years will be 150 - 90 = 60.
So the answer is 60.

Question: Tricia ordered three dozen eggs. She will use 1/4 of them for making crepes, and 2/3 of the remaining for making cupcakes. How many eggs are left to make sunny-side-up eggs for breakfast?
Answer with step-by-step thinking:
Since a dozen is equal to 12, then 3 dozen eggs are equal to 12 x 3 = 36 eggs. Tricia will use 36 x 1 / 4 = 9 eggs for making crepes. So there are 36 - 9 = 27 eggs left. 27 x 2 / 3 = 18 eggs will be used for making cupcakes. Thus, there are only 27 - 18 = 9 eggs left to make sunny - side - up eggs for breakfast.
So the answer is 9.
