Answer:
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
