(b) Cost required for the sixth unit (round your response to the nearest whole number) =

(c) Time required for the seventh unit (round your response to the nearest whole number) =

(d) Cost required for the seventh unit (round your response to the nearest whole number) =

(e) Time required for the eight unit (round your response to the nearest whole number) =

(f) Cost required for the eight unit (round your response to the nearest whole number) =
