A. 55
B. 550
C. 2,695
D. 5,500
E. 26,950

The OA is D.

GIVEN: 385 million dollars represents 7% of TOTAL candy sales
In other words: 7% of TOTAL candy sales = 385 million dollars
Rewrite as: (7/100)(TOTAL candy sales) = 385 million
To multiply both sides by 100/7 to get: TOTAL candy sales = (100/7)(385 million)

ASIDE: We need not perform any complex calculations here.
Notice that the answer choices are VERY spread apart. This means we can be quite AGGRESSIVE with our estimation.
100/7 ≈ 14 and 385 million is close to 400 million
In fact, let's round 100/7 all the way up to 15

We get: TOTAL candy sales ≈ (15)(400 million)
≈6,000 million dollars

Check the answer choices.....only one answer choice is close to 6,000

Answer: D
