 Question 317344: Please Help. I believe that A+B ARE DONE , BUT C IS GIVING ME A PROBLEM. i HAVE WORKED THIS PROBLEM SEVERAL TIMES AND CAN'T FIGURE IT OUT?? Scenario #1: You handle internal accounting for Triad Homes, a land/housing developer. The company purchased land in South Florida and developed 250 acres. Two orders were recently placed with a nursery by the company’s landscapers. The invoices from the orders do not list the per-item price. a) After contacting the Nursery, they inform you that the first order that was placed was for 12 Indian Hawthorn bushes and 5 Maple trees at a cost of \$300.00. Use x to represent bushes and y to represent the trees. Write an equation that illustrates the situation. 12X+5Y=300 <--- IS THIS CORRECT???? b) The Nursery later indicates that the second order called for 6 Indian Hawthorn bushes and 8 Maple trees at a cost of \$315.00. Write an equation that illustrates this situation using the same variables you used in part a. 6X+8Y=315 <----- IS THIS CORRECT? c) Use the equations from parts a and b as a system of equations. Use elimination to determine the cost of each. Describe the steps you used to solve the problem Click here to see answer by stanbon(60771)
