For example, he can make 40 cents by using four 9-cent stamps and a 4-cent stamp, or by using ten 4-cent stamps. However, there are some amounts of postage he can't make exactly, such as 10 cents. What is the largest number of cents that Larry cannot make exactly from a combination of 4- and/or 9-cent stamps?Explain how you know your answer is correct.
