Hello!
The answer is:
The correct answer is c.
![SluggingAverage=(25(1)+10(2)+3(3)+10(40))/(140)=(94bases)/(140times)=0.671](https://img.qammunity.org/2020/formulas/mathematics/high-school/7swyr730vhmoxep5j6y4xw1exjl9bx4mk1.png)
Why?
To calculate the slugging average or slugging percentage, we need to divide the number of total bases by the total times at bat.
![SluggingAverage=(TotalBases)/(TimesAtBat)](https://img.qammunity.org/2020/formulas/mathematics/high-school/quvzl0rujudxo2mw5xpomxff9hmw21qgjs.png)
We know that:
A single means 1 base.
A double means 2 bases.
A triple means 3 bases.
A homerun means 4 bases.
So, we know that:
![Singles=25=25bases\\Doubles=2*10=20bases\\Triples=3*3=9bases\\Homeruns=10*40=40bases\\TimesAtBat=140](https://img.qammunity.org/2020/formulas/mathematics/high-school/t9k4s0br7o70t8qmph45g1tbu33xd7wquk.png)
Then, substituting and calculating we have:
![SluggingAverage=(25bases+20bases+9bases+40bases)/(140)](https://img.qammunity.org/2020/formulas/mathematics/high-school/genrmuxhumlkfjtpydajub6siobi4v3pat.png)
![SluggingAverage=(94bases)/(140times)=0.671](https://img.qammunity.org/2020/formulas/mathematics/high-school/q9c9ps5dsql5yv4zx31q42i1s8zingcv8f.png)
Hence, the correct answer is c.
![SluggingAverage=(25(1)+10(2)+3(3)+10(40))/(140)=(94bases)/(140times)=0.671](https://img.qammunity.org/2020/formulas/mathematics/high-school/7swyr730vhmoxep5j6y4xw1exjl9bx4mk1.png)
Have a nice day!
