Melinda and paul shovel driveways and sidewalks in the winter as a way to earn extra money. together they shoveled 450 square fe
et of sidewalk in 30 minutes. then melinda shoveled for 20 minutes while paul shoveled for 25 minutes to complete 345 square feet of driveway. 30x 30y = 450 20x 25y = 345
From my research the given equations are: 30x + 30y = 450
<span>20x + 25y = 345 </span> The problem asks to solve for the number of square feet Paul has shoveled more than Melinda. This can be solved by using the system of equations to solve for the values of x and y (the respective values of how each they have shoveled each).
Using the system of equations, the following values were obtained: x = 6 y = 9
Therefore, Paul has shoveled 3 square feet per minute more than Melinda.
