📝 Answered - Peter wants to borrow $[tex]$3,000[/tex]$. He has two payment plans to choose from. Plan A charges 4% interest over 6 years. Plan B charges 5% interest over 4 years. The formula [tex]$m=\frac{P+Prt}{12t}$[/tex] can be used to calculate the monthly payment, [tex]$m$[/tex], where [tex]$P$[/tex] is the principle amount borrowed, [tex]$r$[/tex] is the interest rate expressed as a decimal, and [tex]$t$[/tex] is the time of the loan, years. Which statement best compares the plans? A. Plan A has a monthly payment of about $[tex]$23[/tex] less and a total interest charge of $[tex]$120[/tex] less than plan B. B. Plan A has a monthly payment of about $[tex]$23[/tex] less and a total interest charge of $[tex]$120[/tex] more than plan B. C. Plan A has a monthly payment of about $[tex]$23[/tex] more and a total interest charge of $[tex]$120[/tex] more than plan B. D. Plan A has a monthly payment of about $[tex]$23[/tex] more and a total interest charge of $[tex]$120[/tex] less than plan B.

📝 Answered - Is the graph correct? What is the classification of the system? If the graph is not correct, give the correct solution. Hint: Solve each equation for $y$ and check the slopes and $y$-intercepts. If the slopes and $y$-intercepts do not check, then graph each line on paper to find the solution. $\left\{\begin{array}{l} 9 x+6 y=18 \\ 2 y=6-3 x \end{array}\right.$ A) The graph is NOT correct. The classification is Consistent and Dependent. The correct solution is all real numbers. B) The graph IS correct. The classification is Consistent and Dependent.
