Answer:
A. The Federal Trade Commission
Step-by-step explanation:
The FTC inaugurated its doors in March 1915. The FTC's purpose is to protect consumers and encourage contestants.

The FTC states that accusations can improve it and its law implementation partners identify patterns of fraud and exploitation, which may direct to examinations and preventing unfair marketing practices.

Benny got $3.26 back from his purchase
triple 4 means 4 is multiplying with 3 and then add 7 7 times means 7 (7)
3(4) + 7 (7)
= 12 + 49
= 61
So, the expression will be :
3(4) + 7(7)
She is incorrect because 27 is not a prime number but yet it has 7 at the end
