BEFORE you calculate the actual (0.85)(160), scan the answer choices (ALWAYS scan the answer choices, before selecting your approach)
Since the answer choices are VERY SPREAD apart, we can be quite AGGRESSIVE with our estimation.

Notice that 50% of 160 = 80
And 100% of 160 = 160
Since 85% is BETWEEN 50% and 100%, we know that 85% of 160 will be BETWEEN 80 and 160

Answer: C

Cheers,
