Answer:

D

Step-by-step explanation:

A proportional relationship is defined by a linear equation whose y-intercept is zero.

Thus, we immediately reject answers A, B, and C because all involve a non-zero y-intercept.

D is the correct answer. We combine the unit cost $1.75/lb with the shipping fee $0.16/lb, obtaining a unit cost of $1.91/lb.  The desired linear equation with zero y-intercept is then

C(x) = ($1.91/lb)x, where x is the number of pounds of avocados sold.

The situation that represent a proportional relationship is The cost of purchasing avocados for $1.75 per pound plus a shipping fee of $0.16 per pound.

Two variables are said to be proportional if an increase in one variable leads to an increase in the other variable and vice versa.

A proportional relationship is of the form:

y = kx;

where y and x are variables and k is a constant of proportionality

The situation that represent a proportional relationship is The cost of purchasing avocados for $1.75 per pound plus a shipping fee of $0.16 per pound.

Let y represent the cost of purchasing x pounds of avocado, hence:

y = 1.75x + 0.16x = 1.91x

y = 1.91x

This is in the form y = kx.
