<h2>PROBLEM SOLVING</h2>

Let N be the answer to the problem
<h3>Dollars per quart: </h3>
N = 6 ÷ $ 7.49
N = 0.801068091
≈ $ 0.8
↬ $ 0.8 per quart
<h3>Quart per dollar:</h3>
N = $ 9.49 ÷ 6
N = 1.58166667
≈ 1.6
↬ 1.6 quart per dollar

Step-by-step explanation:
Answer:
Volume required = 100mL
Step-by-step explanation:
Let the volume of 30% solution required be = V mL
Amount of solute in V mL of solution = 30% of V = 0.3V...............(i)
This amount is also present in 150 mL of 20% solution
For 150 mL of 20% solution we have amount of solute = 150 mL X 20%
= 30..............(ii)
Thus equating i and ii we get
0.3V = 30
Thus V =100 mL
