Question

Could you possibly figure this out for me​

Answer 1

Answer:

88

Step-by-step explanation:

i used 1980 and 1985. I subtracted 42.1 by 33.4, got 8.7, divided that by 5 since theres been 5 years since, then multiplied by 6 since theres a 6 year difference from 2005 and 2011, then added them.
