must be done in matlab

Problem 6 (15%): Steafan, Edwin, and Tsoukias went to their local electronics store to buy a combination of servos (s), capacitors (c), and resistors (r) for a future robotics project. Unfortunately, the engineers misplaced their receipts but know how much their total costs are for their purchases (without tax). Use the following equations to calculate the unit cost of each component using Matlab. 3s + 4c + 5r = $24.40 5c + 6s + 2r = $30.40 3s + 2c +r=$13.40 a) Identify the coefficient matrix (A) b) Identify the constant matrix (B) c) Solve for the unit cost of each component using A*x=B i. You can check your work by doing the system of linear equations by hand
