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


Answer:
Step-by-step explanation:
Table 1
3:5 , 6 : 10 , 9 :15 , 12 : 20
Table 2
7 : 10 , 14 : 20 , 21 : 30 , 28 : 40
All table 1 Ratios are equal
All table 2 Ratios are equal
3 : 5
= 6 : 10
6 < 7
=> 6 : 10 < 7 : 10
=> 3 : 5 < 7 : 10
=> The ratio 3:5 is less than the ratio 7:10
All table 1 Ratios are equal
All table 2 Ratios are equal
=> All table 1 Ratios are less than the ratios in Table 2
The ratio 14:20 is greater than the ratio 9:15.
