The store owner bought:
12 belts at $108
First step is to calculate the base price for each belt, to do so divide what he paid by the number of belts:
[tex]\frac{108}{12}=9[/tex]To this price he adds up the 45%, so the next step is to calculate the 45% of $9:
[tex]\frac{9\cdot45}{100}=4.05[/tex]Finally add $4.05 to $9 to get the final price per belt:
[tex]9+4.05=13.05[/tex]Each belt will be marked $13.05, the correct answer is C.
