 **Problem 5:** Use Matlab to solve the problem. Suhasini has 44 coins worth %%$%%7.50. They're all quarter, dimes, and nickels. She has twice as many dimes as nickels. How many of each type of coin does she have? Find the answer, and then verify that the solution satisfies the problem.
-**Problem 6:** Use Matlab to solve the following problem. One of the main challenges of this problem is figuring out how to enter the elements of the matrix quickly and reliably. For a small matrix, it's easy to type out the matrix explicitly like ''A = [ 1 9 7 ; 4 3 8 ; 6 2 0]'', but for a 13 x 13 matrix with 169 elements, that's tedious and error prone.
