College Board · Accepted Answer

The correct answer is C. Choice C is correct. Of the 1,300,000 units sold during the first month, 15% were returned, so 1,300,000 × 0.15 = 195,000 units were returned during the first month. If the units were sold and returned at the same rate for the next 5 months, then a total of 195,000 × 6 = 1,170,000 smartphone units were returned during the 6 -month period.
