Answer this question:The area of a forest is three times the area of the square-shaped street. If the street has a length of 100 meters on one side and the number of trees per square meter in the forest is 4, calculate the total number of trees in the forest.
Since the area of a square is sides squared, the area of the square - shaped street is 100 * 100 = 10000 square meters. The area of the forest is three times the area of the square - shaped street, a total of 3 * 10000 = 30000 square meters. If the number of trees per square meter in the forest is 4, there are 4 * 30000 = 120000 trees in the forest.
The answer is 120000.

Answer this question:Dikembe wants to teach everyone at school about the importance of flossing, so he plans to bring enough packets of floss for everyone. There are 20 students in his class. Each student needs 1.5 yards of floss. He sees in the store that each packet of floss contains 35 yards. If he buys the least amount necessary, how much floss is left over?
He will need to bring 30 yards of floss because 20 x 1.5 = 30. One packet of floss is enough because 35 > 30. He has 5 yards left over because 35 - 30 = 5.
The answer is 5.

Answer this question:There were 133 people at a camp. There were 33 more boys than girls. How many girls were at the camp?
If there were 33 fewer boys at camp, there would be the same number of both boys and girls or 133 - 33 = 100 people. That means that there were 100 / 2 = 50 girls at the camp.
The answer is 50.

Answer this question:A plumber is trying to decide which of three different jobs he should take to make the most money. The first job involves fixing three toilets and three sinks at an apartment complex. The second involves two toilets and five sinks at a different apartment complex. The third involves fixing one toilet, two showers and three sinks at a third apartment complex. If the plumber charges $30 to fix a sink, $40 to fix a shower and $50 to fix a toilet, what is the most money the plumber can earn if he can only choose one of these three jobs?
If the plumber chooses the first job, he would earn 3 * 50 + 3 * 30 = $240. If he chooses the second, he'd earn 2 * 50 + 5 * 30 = $250. If he chooses the third, he'd earn 50 + 2 * 40 + 3 * 30 = $220. Therefore, the most money he can earn from one of these jobs is $250.
The answer is 250.
