[Question]On his farm, Mr. Valentino has 200 chickens, twice as many ducks as chickens and three times as many turkeys as ducks. How many birds does Mr. Valentino have on the farm in total?
[Answer]Mr. Valentino has twice as many ducks as chicken on his farm, which means there are 2 * 200 = 400 ducks on the farm. The number of turkeys is three times as many as the number of ducks on Mr. Valentino's farm, a total of 3 * 400 = 1200 turkeys. In total, Mr. Valentino has 1200 + 400 = 1600 ducks and turkeys on his farm. If you add the number of chickens on the farm, the number of birds on the farm becomes 1600 + 200 = 1800 birds. The answer is 1800.

[Question]Michael ran a bakeshop and had to fill an order for 5 peach pies, 4 apple pies and 3 blueberry pies. Each pie recipe called for 3 pounds of fruit each. At the market, produce was on sale for $1.00 per pound for both blueberries and apples. The peaches each cost $2.00 per pound. How much will Michael spend at the market buying the fruit for his pie order?
[Answer]Each pie needs 3 pounds of fruit so for 5 Peach pies, 3 * 5 = 15 pounds of fruit. 3 pounds of fruit for 4 apple pies is 3 * 4 = 12 pounds. 3 pounds of fruit for 3 blueberry pies is 3 * 3 = 9 pounds. He needs 12 pounds of apples and 9 pounds of blueberries so 12 + 9 = 21. 21 pounds of fruit at $1.00 per pound is 21 * 1 = $21.00. 15 pounds of peaches will cost $2.00 per pound so 15 * 2 = $30. The apple and blueberries will cost $21.00 and the peaches will cost $30 so 21 + 30 = $51. The answer is 51.
