Answer:
[tex]x+1\frac{1}{3}=3\frac{2}{3}[/tex]
Step-by-step explanation:
Let the number of cups of onions Katrina still needs to chop = x
She has already chopped the onions = [tex]1\frac{1}{3}[/tex] cups ≈ [tex]\frac{4}{3}[/tex] cups
So total amount of chopped onions = [tex](x+\frac{4}{3})[/tex] cups
Since, onion soup recipe calls for the chopped onions = [tex]3\frac{2}{3}[/tex] cups ≈ [tex]\frac{11}{3}[/tex] cups
Therefore, equation which shows the number of cups of onions to be chopped more will be,
[tex]x+1\frac{1}{3}=3\frac{2}{3}[/tex]
We further solve this equation for the value of x,
x = [tex]\frac{11}{3}-\frac{4}{3}[/tex]
x = [tex]\frac{(11-4)}{3}[/tex]
= [tex]\frac{7}{3}[/tex] cups
≈ [tex]2\frac{1}{3}[/tex] cups
