Answer : The amount of solution needed is, 97.3 fl oz
Explanation :
Let the amount of solution needed be, x
Thus, the equation will be:
[tex](x\times 0.62)+(32-x)\times 0.91=0.90[/tex]
By solving the expression, we get the value of 'x'.
[tex]0.62x+0.91\times 32-0.91x=0.90[/tex]
[tex]0.62x+29.12-0.91x=0.90[/tex]
[tex]-0.29x+29.12=0.90[/tex]
[tex]-0.29x=0.90-29.12[/tex]
[tex]-0.29x=-28.22[/tex]
[tex]0.29x=28.22[/tex]
[tex]x=\frac{28.22}{0.29}[/tex]
[tex]x=97.3[/tex]
Therefore, the amount of solution needed is, 97.3 fl oz
