The density in units of grams per milliliter is 1.0026 g/ml.
<h3>What is density?</h3>
Density is the measurement of how tightly a material is packed together.
Density = mass/volume (kg/m³)
Density = 2.09 lb/quart
1 pound = 0.454 kg = 454 g
1 quart = 946.353 ml
Conversion of the weight in lb/ml to grams per milliliter (g/ml)
= 2.09 lb/quart x 454 g/lb x (1 quart / 946.353 ml)
= 1.0026 g/ml
Thus, the density in units of grams per milliliter is 1.0026 g/ml.

Answer:
Δp = -4 units
Explanation:
For calculating how the quantity of DVRs demanded changes, when the price is modified in one unit, we calculate the derivative of Q with respect to p


This means that when the price increases in one unit the quantity of DVRr demanded reduces in 0.25 units. Then the price must be reduced in 4 units for to obtain one unit more demanded.
