Explanation
Estimate to solve this one.
The answer must be between 12.5 percent and 25 percent because you are mixing two punches with these percentages—eliminate all choices except choices (B) and (C).
Because there is more of Flo’s punch, the answer must be closer to 25 percent than to 12.5 percent, so choice C is correct.

Since 3 L of the 12.5% and 6 L of the 25% are mixed, the result has to be 9 L. To find the percentage:
3(.125) + 6(.25) = 9x
here x = percentage
.375 + 1.5 = 9x
solving for x
x = .2083333
3(.125) + 6(.25) = 9x
here x = percentage
.375 + 1.5 = 9x
solving for x
x = .2083333
