SAT Mathematics Practice Test 7

The percent increase from 2012 to 2013 was $\frac{5,880 - 5,600}{5,600} = 0.05$, or 5%. Since the percent increase from 2012 to 2013 was estimated to be double the percent increase from 2013 to 2014, the percent increase from 2013 to 2014 was expected to be 2.5%. Therefore, the number of subscriptions sold in 2014 is expected to bethe number of subscriptions sold in 2013 multiplied by (1 + 0.025), or 5,880(1.025) = 6,027.
