A 190-pound man and a 130-pound woman went to Burger King for lunch. The man had a BK Big Fish sandwich (750 Cal), medium french fries (400 Cal), and a large Coke (225 Cal). The woman had a basic hamburger (370 Cal), medium french fries (400 Cal), and a diet Coke (0 Cal). After lunch, they start shoveling snow and burn calories at a rate of 420 Cal/h for the woman and 610 Cal/h for the man. Determine how long each one of them needs to shovel snow to burn off the lunch calories. The metabolizable energy contents of different foods are as given in the problem statement. Shoveling snow burns calories at a rate of 420 Cal/h for the woman and 610 Cal/h for the man.

Bethany wrote the equation x+(x+2)+(x+4)=91 when she was told that the sum of three consecutive odd integers had a sum of 91. Which statement about her equation is true? A) Bethany is correct because consecutive odd integers will each have a difference of two. B) Bethany is correct because there are three xs in the equation and three is an odd number so it represents the sum of odd numbers. C) Bethany is incorrect because 2 and 4 are even numbers, she should use 1 and 3 in their place. D) Bethany is incorrect because consecutive integers always increase by 1 each time, not by 2.
