Answer: c) between Qa and Qb
Explanation:
From the exhibit, the lowest cost will be recorded when output is between Qa and Qb because these points represent the lowest costs per unit for Curves A and C and the lowest points where output can be produced. Output being produced at costs lower than this is therefore the lowest for the medium plant.
The best advice for concluding a presentation is by having
to review major points as it is essential to be able to deliver your main
purpose or the important information you want to deliver to your audience and
in the same time, the individual should focus on what he or she wants for his
or her listeners to think, remember and even do.
Option C. If the cross-price elasticity of two goods is negative, then the two goods are <u>complements.</u>

What is Cross-Price Elasticity?
- Cross-price elasticity measures how sensitive the demand of a product is over a shift of a corresponding product price.
- Often, in the market, some goods can relate to one another.
- This may mean a product’s price increase or decrease can positively or negatively affect the other product’s demand.
- A price increase of a complementary product will lead to lower demand or negative cross-price elasticity, and a price increase in a substitute product will lead to increased demand or a positive cross-price elasticity.
- Unrelated products have zero cross-price elasticity.
- For substitute products, an increase in the price of a substitute product increases the demand for the competing product.
- This is often because consumers always try to maximize utility.
- The less they spend on something, the higher the perceived satisfaction.

Answer: 15
Explanation:
For profit to be maximized by a monopolist, the marginal revenue and marginal cost must be gotten.
P= 105-3Q
MC= 15
Since total revenue is price × quantity, TR= P×Q = (105-3Q)Q
= 105Q-3Q^2
MR= 105-6Q
Since we've gotten marginal revenue and marginal cost, we equate both together.
MR=MC
105-6Q = 15
6Q = 105-15
6Q=90
Divide both side by 6
6Q/6 = 90/6
Q= 15
The quantity that will maximise profit is 15
