Roberta wants to have a dinner party centered around soufflés. Each savory souffle calls for 8 eggs each and the dessert ones call for 6 eggs each. She wants to make 3 savory soufflés and 5 dessert soufflés for the party. How many eggs will she need?
Let's think: The savory soufflés need 8 eggs each and she wants to make 3 of these so she needs 8 * 3 = 24 eggs. The dessert soufflés need 6 eggs each and she wants to make 5 of these so she needs 6 * 5 = 30 eggs. For the dinner party she will need 24 + 30 = 54 eggs in total.. The answer is: 54.

The tornado picked up the Smith's car and transported it 200 feet in the air before dropping it into the neighbors' pool. Also in the pool was a lawn chair that had been blown twice as far as the car had been transported. And the pool also contained a birdhouse that had flown through the air three times farther than the lawn chair had been blown. How far, in feet, far had the birdhouse flown?
Let's think: The lawn chair was blown twice as far as the car, or 2 * 200 = 400 feet. The birdhouse had flown 3 times farther than the lawn chair had been blown, or 3 * 400 = 1200 feet.. The answer is: 1200.

Matthias has 40 soccer balls and 15 basketballs. 30 soccer balls and 7 basketballs have a hole in them. How many balls in total does Matthias have without holes in them?
Let's think: Matthias has 40 - 30 = 10 soccer balls without holes. Matthias has 15 - 7 = 8 basketballs without holes. A total of 10 + 8 = 18 balls do not have holes.. The answer is: 18.

John buys 500 newspapers. Each newspaper sells for $2. He sells 80% of them. He buys them all for 75% less than the price at which he sells them. How much profit does he make?
Let's think:
He sells 500 * .8 = 400 newspapers. He sells them for 400 * 2 = $800. He gets a discount of 2 * .75 = $1.5 on the newspapers. So he buys them for 2 - 1.5 = $.5. So he spent 500 * .5 = $250 buying them. That means he made a profit of 800 - 250 = $550.. The answer is: 550.
