Answer:

Option A.

Step-by-step explanation:

The given function is

[tex]f(x)=4.50x+19[/tex]

where, f(x) is the amount Sean pays to his scout club and x is the number of patches.

We need to find the value of f(12).

Substitute x=12 in the given function.

[tex]f(x)=4.50(12)+19[/tex]

[tex]f(x)=54+19[/tex]

[tex]f(x)=73[/tex]

The value of f(12) is 73.

This is the amount Sean pays for earning 12 patches in a month.

Therefore, the correct option is A.
