[Question]Gerald wants to buy a meat pie that costs 2 pfennigs. Gerald has 54 farthings, and there are 6 farthings to a pfennig. How many pfennigs will Gerald have left after buying the pie?
[Answer]First convert the number of farthings Gerald has to pfennigs by dividing by the exchange rate: 54 farthings / 6 farthings / pfennig = 9 pfennigs. Then subtract the cost of the meat pie to find how many pfennigs Gerald has left: 9 pfennigs - 2 pfennigs = 7 pfennigs. The answer is 7.

[Question]Hannah's family has ten pigs on their farm. They also have three fewer than twice as many cows as pigs and six more goats than cows. How many animals do they have on their farm?
[Answer]Twice the number of pigs is 10 x 2 = 20. So, Hannah's family has 20 - 3 = 17 cows. They also have 17 + 6 = 23 goats. So, they have a total of 10 + 17 + 23 = 50 animals on their farm. The answer is 50.

[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?
[Answer]
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 is 230.
