Solution

VerifiedUsing the values from the tables for the relationship of horses and dogs, determine the number of dogs and horses that would fit the total budget of Mr. Hart.

Use ordered pairs $(2,8)$; $(3,11)$; $(4,14)$ and $(5,17)$ to determine the cost of buying dogs and horses. Use the equations, $c = 1,500h + 2,000$ and $b = 500d + 500$.

$\begin{gather*} c = 1,500h + 2,000 = 1,500(8) + 2,000 = 14,000\\ b = 500d + 500 = 500(2) + 500 = 1,500\\ 14,000 + 1,500 = \textbf{15,500} \end{gather*}$

$\begin{gather*} c = 1,500h + 2,000 = 1,500(11) + 2,000 = 18,500\\ b = 500d + 500 = 500(3) + 500 = 2,000 18,500 + 2,000 = \textbf{20,500} \end{gather*}$

$\begin{gather*} c = 1,500h + 2,000 = 1,500(14) + 2,000 = 23,000\\ b = 500d + 500 = 500(4) + 500 = 2,500 23,000 + 2,500 = \textbf{25,500} \end{gather*}$

$\begin{gather*} c = 1,500h + 2,000 = 1,500(17) + 2,000 = 27,500\\ b = 500d + 500 = 500(5) + 500 = 3,000 27,500 + 3,000 = \textbf{30,500} \end{gather*}$

The number of dogs and horses that would fit the total budget of Mr. Hart are $\textbf{4 dogs and 14 horses}$ making the relationship stay the same.
