Billy anderson is choosing between two fitness centers. Center A charges $495 per year for unlimited use of all facilities. Cent
er B charges a $25 sign up fee, a $15 monthly fee, and $5 per aerobics class. If billy goes to aerobics once a week, which club is least expensive for him to use for a year
It would be cheaper for Billy Anderson to go to Center B because the 25 dollar sign up fee plus the 15 dollars a month for 12 months plus 5 dollars a week for 52 weeks is 25+180+260 is 465 so he would save $30 dollars
You have to give them the same denominator so multiply 11/12 by 4 and 3/16 by 3. giving you 44/48 and 9/48. then divied 44 by 9 giving you 4.8888 there for there are 4 whole 3/16 sections of the 11/12 board
