Come up with a question and reasoning that would justify [50] as the answer.
The question is: Eric, Ben, and Jack have some money. Eric has $10 less than Ben, and Ben has $9 less than Jack. If Jack has $26, how much money, in dollars, do all 3 of them have in total?
Reasoning: Ben has 26 - 9 = 17 dollars. Eric has 17 - 10 = 7 dollars. They have 26 + 17 + 7 = 50 dollars in total.

He puts one candle for each year for his grandfather. He puts 27 yellow candles, 14 red candles and the rest are blue candles. How many blue candles did he use?
Reasoning: Caleb has put 27 + 14 = 41 yellow and red candles. So, he used 79 - 41 = 38 blue candles.

The question is: Lisa and Carly go shopping together. Lisa spends $40 on t-shirts then spends half of this amount on jeans and twice this amount on coats. Carly spends only a quarter as much as Lisa on t-shirts but spends 3 times as much on jeans and a quarter of the amount Lisa spent on coats. In dollars, how much did Lisa and Carly spend in total?
Reasoning: Lisa spends $40 on t - shirts / 2 = $20 on jeans. She also spends $40 on t - shirts * 2 = $80 on coats. So Lisa has spent a total of 40 + 20 + 80 = $140. Carly spends $40 / 4 = $10 on t - shirts. She also spends $20 per pair of jeans * 3 = $60 on jeans. She then also spends $80 Lisa’s cost for coats / 4 = $20 on coats. So Carly has spent a total of 10 + 60 + 20 = $90. Lisa and Carly have therefore spent a total of 140 + 90 = $230.
