From the given price function, we have;
(a) 
(b) The point elasticity of demand is 0.0256<u>;</u><u> </u><u>i</u><u>nelastic demand</u>
(c) $46.6
(d) Increase
<h3>How can the elasticity of demand be found?</h3>
a. The given function is presented as follows;

Differentiating the above function with a graphing calculator and setting q = 150 gives;

b. The point elasticity of demand is given by the formula;

When q = 150, we have;
P = 50
Which gives;

The point elasticity of demand, <em>E </em>= <u>0.0256</u>
- The <u>demand is inelastic</u> (less than 1) when the quantity demanded is 150 units
c. If the quantity demanded decreases from 150 to 140 units, we have;

Which gives;
p = 46.6
- The price when the quantity demanded decreases to 140 is <u>$46.6</u>
d. Given that increase in price, from 46.6 to 50, increases the quantity demanded from 140 to 150, therefore;
- The manufacturer should<u> increase the price</u>, <em>p </em>to increase the revenue, <em>R</em>.
R = p × q

Answer:
D.
Step-by-step explanation:
1. Answer A:
15 students signed up for violin lessons (4 boys + 11 girls)
15 / 70 = approx. 21% of the class.
Answer A says 28%, so this is incorrect.
2. Answer B:
17 students signed up for drum lessons (11 boys + 6 girls)
17/70 = approx. 24%
B says 17% signed up for drums, so this is incorrect.
3. Answer C.
Wrong because more girls signed up for piano lessons (15 girls, whereas only 9 boys signed up for piano)
4. D. The same percent of boys and girls are taking guitar lessons.
Get the total number of boys and girls in the class (just add the results for each separately for all instruments)
Boys: 11 + 6 + 9 + 4 = 30
Girls: 6+8+15+11 = 40
6 out of 30 boys signed up for guitar
6/30= 20%
8 out of 40 girls signed up for guitar
8/40 = 20%
Answer is D
