Answer:
Kindly check explanation
Explanation:
Given that:
Swimming cost = $4
Cost of swimming n Times = cost per swim * number of swims
= $4 * n
= $4n
Membership cost = $21
Cost per swim for members = $3
Swimming cost including membership fee :
21 + 3n ; n = number of visits
For 15 visits ; n = 15
Amount paid :
Members = 21 + 3(15) = 21 + 45 = $66
Non - Member = 4(15) = 60
Difference :
$66 - 60 = 6
Members incur $6 more than non - members
