Learning Objective: Approach math test questions strategically
Before you begin making any calculations, see where you can eliminate obviously incorrect answer choices. If the amount of money in the cash register was reduced, the total money in there now cannot exceed the original amount—you can automatically eliminate Choice (D). You are given that the reduced amount is 25% of the original. Look at your choices. Choice (C) looks closer to around 50% than 25%, so you can eliminate it as well. Finally, now that you only have two choices left, you can calculate. Half of $2,200 is $1,100 (50%), and then half of $1,100 is $550 (25%).
Learning Objective: Apply mathematics concepts to law-enforcement scenarios
Two of the vans were full, so that is 2 x 10 = 20 people transported. Then the third van had 4 people, for a total of 20 + 4 = 24 people transported.
Learning Objective: Apply mathematics concepts to law-enforcement scenarios
Write an expression for the elevator trip that starts at the second floor: 2 – 1 + 14 – 6 – 2. The person ended up on the seventh floor.
Learning Objective: Calculate area and perimeter
The perimeter of the building is the sum of all its sides, so 100 feet + 100 feet + 78 feet + 78 feet = 356 feet.
