Question: Mr. Lalande inherited 20,000 euros from his old aunt Adeline. He is very happy because he will be able to afford the car of his dreams, a superb car worth 18000 €. He goes to the dealership and tries the car. He decides to take it, but instead of paying for everything right away, he chooses to pay in several installments. He pays 3,000 euros to be able to leave with the car and the seller offers to let him pay the rest in 6 monthly installments. How much does Mr. Lalande have to pay every month?
Answer: Let’s first calculate what remains to be paid to Mr. Lalande once he leaves the store 18000 - 3000 = 15000£. Let’s split this sum into 6 month installments: 15000 / 6 = 2500£. The answer is 2500.
[Question]Jordan is a hockey goalie. In the first period of a game, he blocked four shots. In the second period, he blocked twice as many shots. In the third period, he blocked three fewer than in the second period. When the game ended after the fourth period, he had blocked 21 shots in all. How many did Jordan block in the fourth period?
[Answer]Let F be the number of shots Jordan blocked in the fourth period. In the second period, he blocked 2 * 4 = 8 shots. In the third period, he blocked 8 - 3 = 5 shots. In the whole game, he blocked 4 + 8 + 5 + F = 17 + F = 21 shots. Thus, Jordan blocked F = 21 - 17 = 4 shots in the fourth period. The answer is 4.

Question: Mr. McNeely takes a register of the total number of students present in class every day. On a particular week, the number of students in the class on the second day was 40 more than the first day. The number of students who didn't turn up for the class on the second day was twice the number of students who didn't turn up on the third day. On the third day, 1/7 of the total number of students of the class called in sick. If the total number of students in the class is 280, calculate the number of absent students in the three days.
Answer:
On the third day, 1 / 7 * 280 = 40 students called in sick. If the number of students absent on the second day was twice the number on the third day, then 2 * 40 = 80 students didn't show up for the class on the second day. The total number of students present in the class on the second day was 280 - 80 = 200. If 40 fewer students showed up for the class on the first day than on the second day, then 200 - 40 = 160 students showed up for the class on the first day. The number of students absent on the first day is 280 - 160 = 120. In the three days, the total number of absentees is 120 + 80 + 40 = 240. The answer is 240.
