[Question]When Diane turns 30, she will be half the age of Alex and twice as old as Allison. Diane is 16 years old now. What is the sum of the ages of Alex and Allison now?
[Answer]When Dianne turns 30, Alex will be 30 x 2 = 60 years old. Allison will be 30 / 2 = 15 years old then. Dianne will turn 30 in 30 - 16 = 14 years. Currently, the age of Alex is 60 - 14 = 46. Currently, Allison is 15 - 14 = 1 year old. So, the sum of Alex and Allison's ages now is 46 + 1 = 47 years old. The answer is 47.
Q: Emily bought a shirt and a coat for $600. What does the shirt cost if it is one-third the price of the coat?
A: Let X be the price of the shirt. The price of the coat is X * 3. The total amount is X + X * 3 = $600. Combining like terms, we get X * 4 = $600. Dividing both sides by 4, we get X = $600 / 4 = $150. The answer is 150.
Question: Leila went to the supermarket to get some groceries. Then she headed to her mechanic to get her automobile fixed. If fixing her automobile cost $350 which was $50 more than thrice the amount she spent at the supermarket, how much has she spent altogether?
Answer: Reversing the steps to obtain the amount she spent at the supermarket, $50 less than $350 is $350 - $50 = $300. If $300 was thrice the amount she spent at the supermarket, then the amount spent at the supermarket was $300 / 3 = $100. In addition to what she spent fixing her auto, she spent $100 + $350 = $450 altogether. The answer is 450.
