Ineed with number 52! and i haven’t done 51

  51.  A/P = (2.2t +25)/(2.6t +29)

  52.  A/P for t=0 is about 0.862

         A/P for t=4 is about 0.858

Step-by-step explanation:

51. The ratio of the two given functions is ...

  r(t) = A/P

  r(t) = (2.2t +25)/(2.6t +29)

__

52. Fill in the required numbers and do the arithmetic.

  r(0) = (0 +25)/(0 +29) = 25/29

  r(0) ≈ 0.862

_

  r(4) = (2.2·4 +25)/(2.6·4 +29) = 33.8/39.4

  r(4) ≈ 0.858

The salary ratio is approximately flat at 0.86 over the 4-year period. It is declining slightly each year.
