this is a compound interest sort of problem
2035 is 25 more years of a 3% increase per year. Rule of 70 says doubling time is 70 (or 72)/rate, so here would expect the doubling to occur in 24 years. Would predict about double
1.03^25=2.0937 increase.
They will be 109.37% higher than they were in 2010.
