You can see that every decade the income increases by 6,250. So if you want to do 5 years instead you would have to add 3,125 to the income of 1980 to find what the income was for 1985. Now you add 33,750+3,125= 36,875. The financial aid cutoff for 1985 would be $36,875.
5.77
By 0.07
Because if you subtract 0.07 from 5.77, you get 5.7, so it must be smaller.

They need to sell 229 more boxes to win.
