For this case, the first thing we must do is define variables.
 We have then:
 x: number of days
 y: amount of money saved
 We then have the following equation that models the problem:
 y = 6x + 34
 Where,
 34: is the initial amount of money that Janna has
 6: amount of money she saves per day
 Answer:
 An equation to represent the relationship between the number of days and amount saved is:
 y = 6x + 34
