Answer:

7. 8200 miles

8. $350

Explanation:

7. The first trip nets 3400 miles; the next four trips (for a total of five) net 1200 miles each, so the total for 5 round trips is ...

... 3400 + 4×1200 = 8200 . . . miles

8. The first month costs $100; the next 5 months (for a total of 6) cost $50 each, so the total for 6 months is ...

... $100 + 5×$50 = $350
