Question

Keshawn bought 16 chicken wings for $28.80. How much would it cost for 9 wings?

Answer 1

Explanation:

I'm assuming this is linear and that there is no special on a larger order of wings. To find the unit price of each piece, divide $28.80 by 16 to get that each piece cost $1.80 (that's a lot for a single chicken wing. That better be one BIG chicken...). To find the cost of 9 wings, multiply 9 by $1.80 to get $16.20

Answer 2

Rule of three

The rule of three is a way to solve problems of proportionality between three known values and one unknown. It establishes a relationship of linearity, proportionality, between the values involved.

We solve by applying the rule of three:

Chicken Wings Price

16------------------------$28.80

9-----------------------------x

First, multiply the number of wings purchased by the given price, divided by the number of wings purchased.

We solve

x = 9 × $28.80 / 16 = 16.2

Answer: 9 wings would cost a total of $16.2
