The level of productivity is now approximately 40.6 boxes/hr
<h3>
What is Productivity</h3>
Productivity refers to a ratio between a output volume and volume of input.
<u>Given data</u>
Working hours = 2*8 hours = 16 hours
New productivity = 500 + 0.3*500
New productivity = 650 box/day
New productivity =650/16 box/hour
New productivity = 40.625 box/hour
Hence, the level of productivity is now approximately 40.6 boxes/hr
Therefore, the Option B is correct.

Answer: (b) -3.08
Explanation:
The relationship between the demand(q), price per unit product(p) and the disposable income,yd is given by the expression below;
q= 20ln(7yd-2p).
From the expression above, the marginal demand,
∂ q/∂ p is the differential of the equation of relationship between the demand, price and disposable income.
This involves considering the demand,q as the dependent variable and the price per unit product,p as the independent variable and the disposable income,yd is considered constant.
Therefore ,
∂ q/∂ p= (-40)÷(7yd-2p)
By substitution of
yd =$3000÷1000= $3
and p= $4
∂ q/∂ p= (-40)÷((7×$3)-(2×$4))
∂ q/∂ p= -40÷13= 3.08
Please see the attachment for knowledge on how ∂ q/∂ p was obtained.
