The football team gained 8 yards on the first play. Lost 6 yards on the next. Gained 3 yards on the third play and lost 12 yards on their final play. What was their final change in yardage after the
four plays?
(HELPP)

-7 yards

Step-by-step explanation:

Might help to line everything up

First play: gained 8 yards (+8)

Second play: lost 6 yards (-6)

Third play: gained 3 yards (+3)

Fourth play: lost 12 yards (-12)

Then put it all together and solve (I'll solve left to right):

(8-6)+3-12

(2+3)-12

5-12

-7

The final change in yardage was -7 yards
