A farmer is selling ducks and chickens at the market. He sells ducks for $10 and chickens for $8. He sells 5 chickens and some ducks. He then spends half his earnings on a new wheelbarrow. After buying it, someone sees it and agrees to pay the farmer double what the farmer paid and the farmer earns another $60. How many ducks did the farmer sell?
Let's think: The wheelbarrow cost $30 because 60 / 2 = 30. The farmer earned $60 from selling fowl because 30 / (1 / 2) = 60. The farmer earned $40 selling chickens because 5 x 8 = 40. The farmer earned $20 selling ducks because 60 - 40 = 20. The farmer sold 2 ducks because 20 / 10 = 2.. The answer is: 2.

A choir was singing a song that involved 30 singers. In the first verse, only half of them sang. In the second verse, a third of the remaining singers joined in. How many people joined in the final third verse that the whole choir sang together?
Let's think: In the first verse, 30 / 2 = 15 singers sang. In the second verse, 15 / 3 = 5 singers joined in. In the final verse, 30 - 15 - 5 = 10 singers joined for the whole choir to sing together.. The answer is: 10.

A store has an 8% discount on all items. If Shara paid $184 for a pair of shoes, how much did Shara save?
Let's think: The price that Shara paid is only 100% - 8% = 92% of the original price. So, every 1% is equal to $184 / 92 = $2. Therefore, Shara saved $2 x 8 = $16.. The answer is: 16.

On Monday a group of 7 children and 5 adults went to the zoo. On Tuesday a group of 4 children and 2 adults went as well. Child tickets cost $3, and adult tickets cost $4. How much money did the zoo make in total for both days?
Let's think:
The total amount of children that went on both days is 7 + 4 = 11. The cost of the children's tickets is 11 × $3 = $33. The total amount of adults that went on both days is 5 + 2 = 7. The cost of the adults' tickets is 7 × $4 = $28. The zoo made $33 + $28 = $61 in total.. The answer is: 61.
