Gamez Inc. makes handheld video game players. Last year, accountants modelled the company's profit using the equation P= -5x² + 60x135. This year, accountants used the equation P= -7x² + 70x 63.

If the same number of game players were sold in these years, did Gamez Inc.'s profit increase? Justify your answer.
