Becky is offered the two deals below. Deal 1: She will get a quarter on the first day of the week. Each day thereafter for one week, she will receive double what she received on the previous day. Deal 2: She will get $4 each day for 1 week. Which statement is true in every aspect regarding these two deals?She should go with deal 1 because mc026-1.jpg is greater than mc026-2.jpg by $3.75.She should go with deal 1 because mc026-3.jpg is greater than mc026-4.jpg by $35.50.She should go with deal 2 becausemc026-5.jpg is greater than mc026-6.jpg by $27.33.She should go with deal 2 because mc026-7.jpg is greater than mc026-8.jpg by $48.50.

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.
