Question

Betty Donahue is choosing between two fitness centers. Center A charges $375 per year for unlimited use of all facilities. Center B charges a $35 sign up fee, a $12 monthly fee, and $5 per aerobics class. If Betty goes to aerobics once a week, which club is least expensive for her to use for a year?

Answer 1

Fitness Center B is the least expensive

Answer 2

Center A would be the least expensive a year.
So,since center A charges a $375 for use of all facilities for a year, that on its own seems like a good offer.
Center B on other hand charges you for a sign up fee $35,a $12 monthly fee,and $5 per aerobics class, she would be paying more.
now let's see,

Center A charges $375 a year for all usage of their facilities.
Center B charges $35 for sign up, a $12 monthly fee, and $5 per aerobics class.

if she were to work out at center B for once a week for year. her total charge for that year would $439.
center A would only be $375. a year.

Hope I helped :-) bye bye.
