Let David's annual income be

**I**.The total tax David pays is $90 + (0.012)×

**I**We also know that David paid a grand total of $846 in taxes.

Therefore $90 + 0.012×

**I =**$8460.012×

**I**= $846 - $90 = $756**∴I**= ($756)/(0.012) = $63,000 per year.

David makes a lot more money than I ever earned! I wish I had majored in whatever he majored in!
