Answer:

B. 8

Step-by-step explanation:

Given the equation, [tex] s = 1.7f - 7.2 [/tex],

where,

s = shoe size,

f = foot length,

To determine the shoe size of a man that has a foot length (f) of 9 in, substitute f = 9 into the equation.

[tex] s = 1.7f - 7.2 [/tex]

[tex] s = 1.7(9) - 7.2 [/tex] (substitution)

[tex] s = 15.3 - 7.2 [/tex]

[tex] s = 15.3 - 7.2 [/tex]

[tex] s = 8.1 [/tex]

His shoe size is approximately 8 inches
