What is the question that you need
Answer:
10
Take 10 and add it 5 times
Step-by-step explanation:
5 divided by 50 is 10
640,000
This is because the vertex of the equation (which can be found by using -b/2a) is (8, 6400). Then you know it is expressed in hundreds of dollars, so you multiply the y term by 100 to get your answer.
