Q: While bird watching, Gabrielle saw 5 robins, 4 cardinals, and 3 blue jays. Chase saw 2 robins, 3 blue jays, and 5 cardinals. How many more birds, in percentage, did Gabrielle saw than Chase?
A: Gabrielle saw 5 + 4 + 3 = 12 birds. Chase saw 2 + 3 + 5 = 10 birds. So, Gabrielle saw 12 - 10 = 2 more birds than Chase. Therefore, Gabrielle saw 2 / 10 x 100% = 20% more birds than Chase. The answer is 20.
Question: William washes cars as a side job. He typically spends 4 minutes washing a car’s windows, 7 minutes washing the car body, 4 minutes cleaning the tires, and 9 minutes waxing the car. This morning he washed 2 normal cars and one big SUV, which took twice as long as a normal car. How many minutes did William spend washing all the vehicles?
Answer: William spends 4 + 7 + 4 + 9 = 24 minutes washing a normal car. He washed 2 normal cars, so he spent 24 * 2 = 48 minutes on the normal cars. He took twice as long as one car for the SUV, so he took 24 * 2 = 48 minutes on the SUV. Thus, William spent 48 + 48 = 96 minutes washing all the vehicles. The answer is 96.
[Question]Loisa wants to buy a tablet that costs $450 cash. Since she does not have enough money, the store offered her an installment plan for 12 months. She will pay $100 as a down payment and pay $40 for the first 4 months; then $35 for the next four months; then $30 for the last four months. How much will Loisa save if she will buy the tablet in cash instead of on installment?
[Answer]Loisa will pay a total of $40 x 4 = $160 for the first 4 months. She will pay a total of $35 x 4 = $140 for the next four months. And she will pay a total of $30 x 4 = $120 for the last four months. Thus, she will pay a total of $100 + $160 + $140 + $120 = $520 for 12 months including the down payment. Therefore, Loisa can save $520 - $450 = $70 if she buys the tablet in cash. The answer is 70.
Q: There are 20 cars lined up at a race. Each of the cars have 2 passengers and a driver, then when the cars go past the race’s halfway point, each car gains another passenger. The cars then continue racing, and the race finishes once every single car has passed the finish line. People who get into the cars have to stay inside of them until the race is finished. How many people are in the cars by the end of the race?
A: There are 2 passengers and a driver in each car, which means that in each car there are 2 passengers + 1 driver = 3 people. This means there are a total of 20 cars * 3 people per car = 60 people in the car at the start of the race. At the halfway point, there is an additional 20 cars * 1 additional passenger = 20 more people. So be the end of the race, there are 60 people at the start of the race + 20 additional people = 80 people in the cars. The answer is 80.
