Step-by-step explanation:

Billy and Maria mow lawns. Billy earned $15 the first day and $20 every day after that. This means the if Billy mowed lawns for x days after the first day, the total amount earned by Billy would be

15 + 20x

Maria earned $10 the first day and $25 every day after that. This means the if Maria mowed lawns for y days after the first day, the total amount earned by Maria would be

10 + 25y

To determine how much each earns after 15 days, it becomes

For Billy, x = 15

Amount earned = 15 + 20*15 = $315

For Maria, y = 15

Amount earned = 10 + 25*15 = $385

Maria earns more than Billy
