Using the definition for the average, and naming each reasut as:
Average = 73
First score = 76
Second score = x-5
Third score= x
Write the equation
[tex]\begin{gathered} 73=\frac{76+(x-5)+(x)}{3} \\ 73=\frac{71+2x}{3} \\ 219=71+2x \\ 148=2x \\ x=\frac{148}{2} \\ x=74 \end{gathered}[/tex]The second score is 69 and the third score is 74.
