14) Note that Carlos travels 12 miles from school to home (and vice versa). Note also that it is only asking for "to school", and for 5 days.
Multiply 5 with 12
12 x 5 = 60
60 miles is your answer.

15) Note:
Mandy travels 9 trips, and each trip is 10 miles
Matt travels 11 trips, and each trip is 8 miles.
Multiply each number to corresponding.
Mandy = 9 x 10
Mandy = 90
Matt = 11 x 8
Matt = 88
Mandy travels more miles than Matt by 2 miles
