4) A company that makes car parts uses two models to estimate the company's profit (in dollars). The first model is P(x) = 90x – 4x², where x is the number of parts produced, and the second model is P(x) = 25x + 170. There are two solutions to the system of equations using both models. Of those two solutions, what is the number of parts that gives the largest profit, and what is that profit? Round the number of parts to the nearest whole number and the profit to the nearest cent.​
