Answer:
1. <u>$14.88</u>
2. <u>$12.40</u>
Step-by-step explanation:
An english translation:
<em>A company transports office cabinets to a location 425km away. Its cost is R $ 2.10 per km traveled. When the cabinets are assembled, the vehicle's capacity is 60 units. When they are disassembled the capacity increases 6 times. We ask: 1- What is the cost per assembled cabinet? 2- What is the savings per cabinet, when these are taken apart.</em>

<u>Solution:</u>
425 km with 2.10 per km means:
425 * 2.10 = $892.50 total cost
Now, when assembled, there goes 60 cabinets, so cost per assembled cabinet is:
<u>Cost per assembled cabinet = 892.5/60 = $14.875 = $14.88</u>
<u></u>
The capacity of 60 after disembling, it becomes:
60 * 6 = 360
So, cost per cabinet becomes:
892.5/360 = <u>$2.48</u>
The savings is how much you save up if they were assembled:
14.88 - 2.48 = <u>$12.40</u>
<u>Savings = $12.40</u>
Scenarios B, D, and F require a police officer. In scenario B, 1:00-2:00pm, and scenario F, 5:00-6:00pm, there are 24 cars. In scenario D, 3:00-4:00pm, there are 21 cars. Both 24 and 21 are greater than 17, so a traffic officer is needed. However, in other scenarios, the number of cars are all less than 17, and no officer is needed.

Answer:
The equivalent percentage point drop = 10%
Step-by-step explanation:
The percentage point change is the difference between the final and initial values.
The percentage change is the difference between the final and initial values
divided by the initial value
It is required to decrease the dropout rate from 30% to 20%
The point change = 20 - 30 = -10 (-ve change ⇒ decrease)
The percentage change = 
%
So, the equivalent percentage point drop = <u>10%</u>
And the percentage change = <u>33.33%</u>
