Frankie taught 3 * 2 = 6 classes. Combined, Frankie and Eduardo taught 3 + 6 = 9 classes.
The answer: 9
Reverse engineering the question: Eduardo is a teacher. He taught 3 classes last week while his colleague Frankie taught double what Eduardo teaches. How many classes did Eduardo and Frankie teach in total?

The sum is 9 + 14 + 13 = 36. There are 3 bouquets. The average is 36 / 3 = 12.
The answer: 12
Reverse engineering the question: Trevor buys several bouquets of carnations. The first included 9 carnations; the second included 14 carnations; the third included 13 carnations. What is the average number of carnations in the bouquets?

There are 5 - 1 = 4 more lions each month. There will be 4 * 12 = 48 more lions after 1 year. There were 148 - 48 = 100 lions in Londolozi at first.
The answer: 100
Reverse engineering the question: There are some lions in Londolozi at first. Lion cubs are born at the rate of 5 per month and lions die at the rate of 1 per month. If there are 148 lions in Londolozi after 1 year, how many lions were there in Londolozi at first?

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.
The answer: 230
Reverse engineering the question:
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?
