On the last play, then they lose 15 yards. What yard line are they on now? A They are on the 22 yard line, because -20 + 10 + 7 + 5 + 15 - 22. . B They are on the 42 yard line, because 10 + 7 + 5 + 15 = 42. C They are on the 7 yard line, because 20 + (-10) + 7 + 5+ (-15) = 7. D They are on the 13 yard line, because -10 + 7 + 5+ (-15) = -13.

Answer 1

SOLUTION.

The team started on a 20 yards line, then they lose yards.

This makes it 20 - 10 or 20 + (-10) = 10 yards remaining

The next play, they gained 7 yars.

This makes it 20 + (-10) + 7 = 17 yards remaining

Then they gained another 5 yards.

This makes it 20 + (-10) + 7 + 5 = 22 yards remaining.

On the last play, they lose 15 yards.

This makes it 20 + (-10) + 7 + 5 - 15 or

20 + (-10) + 7 + 5 + (-15) = 7 yards remaining.

Therefore from our explanation, the correct answer is option C.

C. They are on the 7 yard line, because 20 + (-10) + 7 + 5+ (-15) = 7.
