Q: LaKeisha is mowing lawns to raise money for a collector set of books. She charges $.10 for every square foot of lawn. The book set costs $150. If she has already mowed three 20 x 15 foot lawns, how many more square feet does she have to mow to earn enough for the book set?
A: She has mowed 900 square feet because 3 x 20 x 15 = 900. She has earned $90 because 900 x .1 = 90. She has to earn $60 more dollars because 150 - 90 = 60. She has to mow 600 more square feet of lawns because 60 / .1 = 600. The answer is 600.
Question: Jenny is older than Charlie by five years, while Charlie is older than Bobby by three years. How old will Charlie be when Jenny becomes twice as old as Bobby?
Answer: Jenny is older than Charlie by 5 years who is older than Bobby by 3 years, so Jenny is older than Bobby by 5 + 3 = 8 years. Jenny will be twice as old as Bobby when he is 8 * 2 = 16 years old. Jenny is 5 years older than Charlie so when Jenny is 16, Charlie will be 16 - 5 = 11 years old. The answer is 11.
