Suppose that with a certain phone company, an international long distance phone call from Canada to Brazil costs $0.90 for the first minute (up to and including 60 seconds), plus $0.50 for each additional minute or part of a minute. Note: "Part of a minute" means that if a new minute is started even just by one second, a full minute is charged. For example, a 5 min 1 sec phone call costs the same as a 5 min 50 sec phone call and the same as a 6 min O sec phone call. Suppose C (t) is the function that gives the cost of making at minute long phone call. On a piece of paper, sketch a graph showing C (t) (with C on the y-axis and t on the x-axis). Then use your graph to evaluate each of the following: (Write DNE for undefined.) C (2.5) =| [ Select] C (4) = [ Select ] lim C (t) = [ Select ] z-3.1 lim C (t) = [ Select] lim C (t) = [ Select] z¬4* [ Select ] lim C (t)
