SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Write the representation of the chicken wings
Let the chicken wing be represented by x
[tex]\begin{gathered} For\text{ Customer 1, he spent;} \\ 8x+4 \\ From\text{ second customer, he spent} \\ 10x+2.50 \end{gathered}[/tex]STEP 2: Equate the two amounts
Since they both spent same amount of money, this means that;
[tex]8x+4=10x+2.50[/tex]STEP 3: Solve for x
[tex]\begin{gathered} Collecting\text{ like terms:} \\ 8x-10x=2.50-4 \\ -2x=-1.5 \\ Divide\text{ both sides by -2} \\ \frac{-2x}{-2}=\frac{-1.5}{-2} \\ x=0.75 \end{gathered}[/tex]Hence, each chicken wing costs $0.75
