Answer:
The loss on the sale of 50 type M cars is $8000, and the loss is decreasing at the rate of $500 per 50 type M car sold.
Step-by-step explanation:
Given


Required
Interpret
From the question, we understand that:
Number of cars
Profit on x cars
Using the above as a point of reference,
Rate of loss per x cars
So, the interpretations are:

A loss of 8000 on 50 cars

The loss rate is a reduction of 500 per 50 car
Box 1 : 3 pencils + 7 pens = total of 10
probability of picking a pen is 7/10
box 2 : 3 pencils + 3 crayons = total of 6
probability of picking a crayon is 3/6 which reduces to 1/2
probability of picking both is (7/10 * 1/2) = 7/20 <==
The short answer: yes.
