The italian size of a suit jacket is n centimeters, where n is the linear distance between the armpits. the american size of a suit jacket is 2.5p centimeters, where 2.5p is twice the linear distance between the armpits. if, for a particular jacket, n = p + 10, which of the following is closest to the value of n? (one inch is approximately 2.54 centimeters.)
a) 36b) 47c) 58d) 65e) 72

  B)  47

Step-by-step explanation:

If we assume the 2.5P is more accurately 2.54P, then we have two relations between N and P:

Solving the second for P gives ...

   P = N -10

and substituting that into the first gives ...

  2.54(N -10) = 2N

  0.54N -25.4 = 0 . . . . . . subtract 2N

  N -47.037... = 0 . . . . . . .divide by 0.54

  N ≈ 47 . . . . . . . . . . . . . . add 47.037... and round

The closest value of N is 47.

Comment on the problem

If you take the problem at face value, you compute N=50. The closest offered answer is still 47. In this scenario, the relationship between inches and centimeters is irrelevant, as there are no inches anywhere in the problem.
