Answer:
C. 24
Step-by-step explanation:
by algebra:
let "?" be x
35/30 = 28 / x (multiply both sides by 30)
35 = (28/x) (30) (multiply both sides by x)
35x = (28)(30)
35x = 840 (divide both sides by 35)
x = 840 / 35
x = 24

Answer:
69090840 possible rankings
Step-by-step explanation:
The number of possible ranking ordered in terms of effectiveness can be obtained using permutation
Number of salesperson = 39
Number of rank = 5
nPr = n! ÷ (n - r)!
nPr = 39P5
39P5 = 39! ÷ (39 - 5)!
39P5 = 39! ÷ 34!
39P5 = 39 * 38 * 37 * 36 * 35 = 69090840
