Leah loves chicken a wings and is comparing the deals at three diffrent restaurants. buffalo bills has 8 wings for $7 .buffalo milds wings has 12 wings for $10 .wingers has 20 wings for $17 .which restaurant offers the lowest price per wing?

For each, divide the amount by the number of wings

7 divided by 8: 0.875 = $0.88 per wing

10 divided by 12: 0.8333 = $0.83 per wing

17 divided by 20: 0.85 = $0.85 per wing

Looking at each result, the middle one (the $10 for 12 wings) is the best deal

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

is this part of a question or something
