During the summer, winnie delivers flowers and bob babysits for neighbors. to show their earnings, winnie makes a graph and bob makes a table. which statement is true?

The first thing we must do for this case is to look for the linear function of the bob's earnings.
 The slope is:
 m = (93.60-46.80) / (6-3)
 m = 15.6
 Then, the linear equation is:
 y = 15.6x
 Therefore, we observe that Bob has more earnings per hour than Winnie because the slope of the line is higher (15.6> 11.5)
 
 Bob has more earnings per hour than Winnie because the slope of the line is higher (15.6> 11.5)
