2. A truck carrying a cargo of 10,000 pounds of gravel is traveling down a bumpy road. The truck (which is old, and which was formerly owned by Fred Sanford, who didn't take good care of it) loses 15 pounds of gravel per mile. How far will the truck have traveled by the time its remaining cargo weighs 9,750 pounds?

3. The same truck (as in the previous question) had traveled 40 miles prior to its cargo being reduced to 10,000 pounds. How much did its original cargo weigh?

4. The same truck eventually is down to a cargo weight of 9,000 pounds, at which point it begins to lose an additional 2.5 pounds of gravel per mile every 10 miles. How much will the truck weigh when it has traveled an additional 30 miles?
