A school is planning a field trip and estimates that the cost per student decreases as more students sign up. If the cost per student is $50 for 10 students and $40 for 20 students, create a linear equation to model the cost per student (C) based on the number of students (n). What is the cost per student if 15 students sign up?

A smartphone company finds that for every $50 increase in price, they sell 100 fewer units. If the current price is $300 and they sell 1,000 units, write a linear equation to represent the relationship between price (p) and units sold (u). How many units will they sell if the price is raised to $400?
