Jill's Spending and Graph Analysis

The video tutorial explains how to calculate and graph the amount of money Jill has over time using the formula y = 40 - 2.5x. It starts with an introduction to the problem, followed by creating a table of values to plot the graph. The tutorial then calculates Jill's money over different days and finally graphs the equation to visualize the changes in her money over time. The graph shows that Jill will have $20 left after 8 days.
