the answer to this problem 19
The number of Grade 6 students were asked in total is 100 students.
<h3>How to calculate the value?</h3>
Let the number of students who choose Natural History be x.
Since the number of students who chose the Museum of Math was 50 more than the number of students who chose the Museum of Natural History. This will be x + 50
The ratio of students who chose the Museum of Math to students who chose the Museum of Natural History was 3 to 1. The expression will be illustrated thus:
1/3 = x/x+50
Cross multiply
3x = x + 50
Collect like terms
3x - x = 50.
2x = 50
Divide
x = 50/2
x = 25
Also, x + 50 = 25 + 50 = 75
The number of Grade 6 students that were asked will be:
= 25 + 75
= 100

Answer:
We are given that a manufacturer sells a product as $2 per unit.
Quantity = q units
So, Total revenue = 
Total revenue = 
So, the total revenue function is 
Marginal revenue is the derivative of the revenue functions
So, Marginal revenue = 
The marginal revenue function is 2
The constant marginal revenue function mean that the revenue earned by the addition of the output is constant.
