b. Use the greedy algorithm to make change for $1.48. Assume (.25, .10, .05,.01: 1.48) State your answer in terms of the numbers of each coin. Show each step in the algorithm for credit. c. Use the greedy algorithm for (.25, .05, .01: 1.48). d. What is the difference in the total number of coins between those two uses of the greedy algorithm?
