There are 4 quarters in 1 dollar. The total number of dollars is a function of the number of quarters. Does this situation represent a linear or nonlinear function? Explain why

⇒⇒It is "linear relationship"

Step-by-step explanation:

⇒⇒It is so because whatever you do to the number of dollars, you also do the same to get the number of corresponding quarters.

⇒⇒We say that the constant of proportionality is 4 (or 1/4), as in

⇒⇒Q = 4D or

⇒⇒D = f(Q) = Q/4

⇒⇒This is graphed as a straight line.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
