To maximize profit, the firm will hire labor up to the point where the marginal product of labor equals the ratio of the price of output to the cost per unit of labor (i.e., MP = P/C). In this case, the marginal product of labor can be found by taking the partial derivative of the production function with respect to L:

MP = F1F1F10 6S1U1P12/3S1S1P0

Setting this equal to the ratio of the price of output to the cost per unit of labor, we get:

F1F1F10 6S1U1P12/3S1S1P0 = 16/16

Simplifying, we get:

F1F1F10 6S1U1P12/3S1S1P0 = 1

Taking the natural logarithm of both sides, we get:

ln(F1F1F10) + (2/3)ln(P12) + ln(S1U1) - ln(S1S1P0) - 6ln(L) = 0

Solving for L, we get:

L = e^(ln(F1F1F10) + (2/3)ln(P12) + ln(S1U1) - ln(S1S1P0) - 6ln(16))

L = e^(ln(F1F1F10) + (2/3)ln(P12) + ln(S1U1) - ln(S1S1P0) - ln(2^6))

L = e^(ln(F1F1F10) + (1/3)ln(P12) + ln(S1U1) - ln(S1S1P0) - ln(2^3))

L = e^[ln(F1F1F10P12^(1/3)S1U1/S1S1)/8]

Plugging in the given values, we get:

L = e^[ln(FF1F1S1^3U1P12)/(8S1S1))/8]

L = e^[ln(FF1F1S1^3U1P12)/(8S1S1^2))/8]

L = e^[ln(FF1F1S1^3U1P12)/(8S1^3))/8]

L = e^[ln(F1F1F10) + (1/3)ln(P12) + ln(S1U1) - ln(S1S1P0) - ln(2^3) - ln(16/16)]

L = e^[ln(F1F1F10) + (1/3)ln(P12) + ln(S1U1) - ln(S1S1P0) - ln(2)]

Using the given production function and simplifying, we get:

L = e^[(3/2)ln(2) - ln(16) - ln(P) + ln(FFF1) - ln(S1U1) + ln(S1S1P0)]

Plugging in the given values, we get:

L = e^[(3/2)ln(2) - ln(16) - ln(16) + ln(FFF1) - ln(S1U1) + ln(S1S1)]

Since we don't have specific values for F1, S1, or U1, we cannot calculate L exactly. However, we can see that L is positively related to F and S, and negatively related to U. Therefore, if we assume that F and S are relatively high and U is relatively low, we can deduce that L will be relatively high. The closest answer choice to this prediction is B) 64.
