4 "Kettenmails" belasten das Mailsystem unnötig, sind eigentlich kaum sinnvoll und funktionieren in den wenigsten Fällen so, wie es versprochen wird. a In der Startrunde einer «Kettenmail» erhalten vier Personen eine E-Mail

(a) Find the new cost of the frozen pizza after 12 years. Round your answer to the nearest cent. The new cost of the frozen pizza after 12 years is \( \$ 9.34 \). Part: \( \mathbf{1 / 2} \) Part 2 of 2 (b) If, on the other hand, the cost of the frozen pizza increased by \( 5 \% \) of the original cost each year for 1 . from part (a)? Round all intermediate calculations and the final answer to the nearest cent. The frozen pizza would cost \( \$ \square \) less
