What approximate value will come in place of the question mark (?) in the following question? 30.06% of 499 + 39.99% of 799 = ?

Approximate the expression to 30 percent of 500 plus 40 percent of 800. Calculate 30 percent of 500 to get 150, and calculate 40 percent of 800 to get 320. Adding 150 and 320 gives a result of 470.
