Answer:
Part A) 
Part B) 
Part C) 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
Let
x -----> the number of workers
y ----> the number of pieces made
In this problem
The relation between the variables x and y represent a direct variation (proportional variation)
so
For x=16, y=40
Find the value of the constant of proportionality k
substitute the values

The linear equation is equal to

Part A) How many workers are needed to make 20 pieces
For y=20 pieces
substitute in the linear equation


Part B) How many workers are needed to make 25 pieces
For y=25 pieces
substitute in the linear equation


Part C) How many workers are needed to make 100 pieces
For y=100 pieces
substitute in the linear equation

Given:
<span>43 students in his school liked skating and 21 of those students liked swimming, as well
</span><span>7 students who did not like skating but liked swimming
</span><span>6 students who liked neither skating nor swimming
Like skating Not like skating Total
Like swimming 21 7 28
Not like swimming 22 6 28
Total 43 13 56
All the bold numbers are the missing details. The regular numbers are the given numbers.
That is the table I came up with because the given choices are not understandable.

Answer: A) 7.5%
Step-by-step explanation: You can simply add 7.5% of 283 (which is 21.225) to 283 itself and it’ll come out to 304.225 which is close enough. You do the same with 304.25 and you’ll get 327.06 which again, is closer than any other answer
