A scientist needs to print a research report on her computer’s printer. If she prints in black ink only, b(t)=152-33t describes the number of pages left to print after t minutes. If she prints in colored ink, c(t)=152-30t describes the number of pages left to print after t minutes. Based on this information, which statement is true?F. The printer prints 3 more pages per minute in colored ink than in black ink.G. The printer prints 3 fewer pages per minute in colored ink than in black ink.H. The printer prints the same number of pages per minute in either type of ink.J. The printer prints the entire research report in 152 minutes.
