Which best describes how specialized producers decrease their opportunity costs?
O by reducing production costs
O by focusing on target markets
O by increasing production of certain items
O by limiting the types of goods produced

"By limiting the types of goods produced" best describes how specialized producers decrease their opportunity costs.

Option: D

Explanation:

Opportunity costs reflect the advantages that a person, investor or company loses when selecting an alternative over another option.By restricting the types of products manufactured by specialist producers their opportunity costs can be reduced. It is important to remember that a supplier with a competitive advantage can deliver a product or service at a lower cost of production than any competitor can. The root of increasing cost of opportunity lies with the abundance of capital. Opportunity costs increase as demand increases, while output decreases as demand decreases.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
