You can solve this problem using a ratio.
Variable P%5B1%5D will be the 150 pound person, and variable P%5B2%5D will be the 100 pound person.
Variable C%5B1%5D will be the 100 calories burned, and varible C%5B2%5D will be the unknown.
So, set up the ratio.
P%5B1%5D%2FC%5B1%5D=P%5B2%5D%2FC%5B2%5D
Replace the variables with known numbers.
150%2F100=100%2FC%5B2%5D
Cross multiply to solve for C%5B2%5D
150%2AC%5B2%5D=10000
10000%2F150=C%5B2%5D
C%5B2%5D=66.666
Hope this helps!
