I need help with a school assignment. The assignment has given me 3 students that have taken a multiple choice test with the answers either "a", "b" or "c" along with the answer key. I need a formula that does the following: "write functions that will grade each answer, giving 1 point for a correct answer and 0 otherwise. Assume that all answers are in lowercase letters, therefore, the function that tests the answer to the first question should check for a "c" rather than a "C". Basically, I need a formula that will display a "1" if the answer is correct and a "0" if it's incorrect. This is for an online school assignment and I've gone everywhere I can think of and the instructions on how to create this function just aren't there, not even in the 900+ page book. PLEASE HELP
