Four years ago, Kody was only half as old as Mohamed. If Mohamed is currently twice 30 years old, how old is Kody? Give the rationale and then the answer.
Let's think step by step. Mohammed is currently 2 * 30 = 60 years old. four years ago, Mohammed was 60 - 4 = 56 years old. Four years ago, Kody was half Mohammed's age, which is 56 / 2 = 28 years old. Currently, Kody is 28 + 4 = 32 years old.. The answer is: 32.

Carmen is selling girl scout cookies. She sells three boxes of samoas to the green house for $4 each; two boxes of thin mints for $3.50 each and one box of fudge delights for $5 to the yellow house; and nine boxes of sugar cookies for $2 each to the brown house.
