An audio books club charges an initial joining fee of $15.00. the cost per audio book is $12.00. the graph shows the cost of belonging to the club as a function of audio books purchased. how will the graph change if the cost per audio book goes up by $1.00?

Pleasse me i need an answer. give me the correct answer. answer if you know it ! the club will base its decision about whether to increase the budget for the indoor rock climbing facility on the analysis of its usage. the decision to increase the budget will depend on whether members are using the indoor facility at least two times a week. use the best measure of center for both data sets to determine whether the club should increase the budget. assume there are four weeks in a month. if you think the data is inconclusive, explain why.
