To solve this problem, we need to divide the total number of hours the assembly line runs by the length of each shift:
9 3/4 ÷ 3/4
To make the denominator the same, we can convert the whole number to a fraction:
39/4 ÷ 3/4
Now we can divide by multiplying by the reciprocal:
39/4 x 4/3 = 13
Therefore, there are 13 shifts each day. Answer choice D is correct.
