to health clubs offer different membership plans the graph to the right of the total cost of belonging to club a and club b for a year math

Answer 1

Usually this type of problem asks which club is cheaper

or when do the plans cost the same for each club

usually there's a monthly fee plus another fee per day or per hour

so, for example

club A charges a $40 monthly fee plus $1 per hour

club B charges $10 monthly fee plus $2 per hour

they will cost the same when

40+h = 20+2h

20 = h = 20 hours

if you are using the club more than 20 hours per month, then Club A is cheaper

use less than 20 hours per month and Club B is cheaper

use the club 10 hours per month then club a costs$50 while club b costs $30
