B $7$7
C $8$8
D $9
To find the marked down price of the baseballs, we need to find the percentage decrease of the baseball bats.
The markdown of the baseball bat is $15, and its regular price is $60.
The percentage decrease can be found by dividing the markdown by the regular price and multiplying by 100:
$\frac{15}{60} \cdot 100 = 25$
Therefore, the percentage decrease is 25%.
To find the marked down price of the baseballs, we need to apply the same percentage decrease.
The original price of the baseballs is $12.
The markdown of the baseballs can be found by multiplying the original price by the percentage decrease and then subtracting it from the original price:
$12 - (\frac{25}{100} \cdot 12) = 12 - 3 = 9$
Therefore, the marked down price of the baseballs is $9.
D. $9
