One and a half increase in the productivity in Tutuwanas saw-mill this year was due to the Albaszu machine's being finally repaired. If the Albaszu machine was cutting 10 trees daily, how many trees is it cutting now after its improvement? Give the rationale and then the answer.
Let's think step by step. The increase in productivity of the Albaszu machine was one and a half, which is 1 1 / 2 or 3 / 2. This means there was an increase of 3 / 2 * 10 = 15 trees that the machine was cutting after it was repaired. Currently, the Albaszu machine is cutting 15 + 10 = 25 trees each day.. The answer is: 25.

Avery puts 4 shirts in the donation box. He adds twice as many pants as shirts in the box. He throws in half as many shorts as pants in the box. In total, how many pieces of clothes is Avery donating? Give the rationale and then the answer.
Let's think step by step. The total number of shirts in the donation box is 4. The total number of pants in the donation box is 4 x 2 = 8. The total number of shorts in the donation box is 8 / 2 = 4. The total number of clothes donated is 4 + 8 + 4 = 16 pieces.. The answer is: 16.

The price of buying a wooden toy at the new Craftee And Best store is $20, and the cost of buying a hat is $10. If Kendra went to the shop with a $100 bill and bought two wooden toys and three hats, calculate the change she received. Give the rationale and then the answer.
Let's think step by step. When Kendra bought 2 toys, she paid 2 * $20 = $40. Since the price of a hat is $10, when Kendra bought 3 hats, she paid 3 * $10 = $30. The total costs for the hats and wooden toys Kendra bought is $40 + $30 = $70. From the $100 bill, Kendra received change worth $100 - $70 = $30.. The answer is: 30.
