To make a shed in his backyard, Tom needs 1000 bricks. He can buy half of the bricks for 50% off of $.50. The other Half he needs to pay full price. How many dollars does Tom spend?
Let's think: Tom can buy 1000 / 2 = 500 for half price. He will spend $.50 / 2 = $.25 on the half - priced bricks. Thus, he will spend 500 * $.25 = $125 on the half - priced bricks. He will spend 500 * $.50 = $250 on the full - priced bricks. Thus, he will spend $125 + $250 = $375 total.. The answer is: 375.

Four people lost a total of 103 kilograms of weight. The first person lost 27 kilograms. The second person lost 7 kilograms less than the first person. The two remaining people lost the same amount. How many kilograms did each of the last two people lose?
Let's think: Second person = 27 - 7 = 20 kg. 103 - 27 - 20 = 56 kg. 56 / 2 = 28 kg. The last two people each lost 28 kilograms of weight.. The answer is: 28.

There are three goldfish and ten platyfish in a fish tank. Each goldfish plays with ten red balls, while each platyfish plays with five white balls. What is the total number of balls in the fish tank?
Let's think: If there are 3 goldfish, and each is playing with ten red balls, then the number of red balls in the tank is 3 * 10 = 30. There are also ten platyfish playing with 5 white balls, there are 10 * 5 = 50 white balls. The total number of red and white balls in the fish tank is 50 + 30 = 80.. The answer is: 80.

Laura is hosting a carwash. She will charge $5 for a car, $6 for a truck, and $7 for an SUV. They raised $100 in total. If they washed 5 SUVs and 5 trucks, how many cars did they wash?

They earned $30 from trucks because 5 x 6 = 30. They earned $35 from SUVs because 5 x 7 = 35. They earned $35 from cars because 100 - 35 - 30 = 35. They washed 7 cars because 35 / 5 = 7.. The answer is: 7.
