An increase in the price of milk causes a decrease in the demand for cereal. the two products are a. substitutes. c. unrelated. b. complements. d. demand elastic.

The correct answer is B. Complements

Explanation:

In economics and related, the term "complements" is used to describe products or services that are closely related as these are often consumed together. Due to this, the increase or decrease in demand, supply or price will often affect complements similarly.

This concept applies to milk and cereal because many people consume these two products together; also, an increase in the price of one causes a decrease in the demand of the other as people are less likely to buy cereal if milk is more expensive and vice versa. Thus, the two products are complements.

x=3

step-by-step explanation:

this is really simple i saw that there was only one term (5x) and thought if that was 15 what would i have to multiply everything else to get it there? well if 5x became 15 then x would have to be 3 so plug the 3 in the x for the other equations and you get 15 for the other ones. so there you go. : )
