    for B you need to set the equations equal to each other and solve for x 2020-125x=1075+80x

    2020-125x=1075+80x Solve for x and there is the time it will take them to become the same.

    yes. you should probably write that as a decimal and round to the nearest whole. Can't have part of a student

    Learning is good and don't feel bad if you don't know something, someone's always around to help you out. Actually, this was a bit of a learning experience for me?
