Question: Cecil has $600. Catherine has $250 less than twice as much as Cecil while Carmela has $50 more than twice Cecil's money. How much money do they have altogether?
Answer: Twice as much as Cecil's money is $600 x 2 = $1200. So, Catherine has $1200 - $250 = $950. While Carmela has $1200 + $50 = $1250. Hence, they have a total of $600 + $950 + $1250 = $2800. The answer is 2800.

Question: John is 10 years old. His sister is twice his age. When he is 50 years old, how old will his sister be?
Answer: His sister is 10 * 2 = 20 years old. Their age difference is 20 - 10 = 10 years. Therefore when he is 50 she will be 50 + 10 = 60 years old. The answer is 60.

Question: Two white socks cost 25 cents more than a single brown sock. If two white socks cost 45 cents, how much would you pay for 15 brown socks?

Question: Mabel has 5 daisies in her garden, and each daisy has 8 petals. If she gives 2 daisies to her teacher, how many petals does she have on the remaining daisies in her garden?
