First, let's formulate an equation. Let the independent variable be x to denote the number of hours. The dependent variable is y to denote the total cost. The equation should be:

y = 25x + 50

The table and graph is shown in the picture. Just use values of x as 1, 2, 3 and 4, find y and plot the points.
