So the range is that combined sugar and chocolate chips you can have [1,10/3] cups.
So far, you have already poured in three and three quarters which in improper fractions is 15/4. Multiply the y-range of the combined with 4, to get this:
12/12 => 40/12. Then multiply 15/4 by three to get 45/12. Clearly you see this that more cups of sugar than the limit is poured. you can only go to 40/12, but 45/12 is just sugar, so no chocolate chips can be added
I’m pretty sure it’s answer a!

Answer:
1.1 quarts
Step-by-step explanation:
Let x represent the amount to be added, in quarts. Then the amount of anti-freeze in the resulting solution is ...
0.20(8) + 1.00(x) = 0.30(8 +x)
0.70x = 0.10(8) . . . . . . subtract 0.20(8)+0.30(x)
x = 8/7 . . . . . . . . . . . . . divide by the coefficient of x
x ≈ 1.142857 ≈ 1.1
About 1.1 quarts of pure antifreeze must be added.
