You are choosing between two health clubs. club a offers membership for a fee of $ $11 plus a monthly fee of $ $19. club b offers membership for a fee of $15 plus a monthly fee of $18. after how many months will the total cost of each health club be the same? what will be the total cost for each club?

Using the variable m for month
Club A:                                                      Club B:
 19m+11         19m+11=18m+15                          18m+15
                        -18m       -18m
                         m+11=  15  
                            -11     -11
                             m=4
Check 19(4)+11 = 87     18(4)+15= 87
total cost = 87

Club A is 11+19m Club B is 15+18m When they cost the same the two expressions are equal so: 11+19m = 15+18m M. = 4 In 4 months the two health clubs will cost the same amount. The cost of each club is $87.
