Human: Keaton has a farm of oranges and apples. He can harvest his oranges every 2 months and can sell the harvest for $50.  He can harvest his apples every 3 months and can sell this harvest for $30. How much money can Keaton earn every year? Assistant:
Keaton can harvest his oranges every year is 12/2=6 times.
So the total money he earns for his oranges every year is $50 x 6 = 300.
He can harvest his apples 12/3= 4 times in a year.
So the total money he earns for the apple in a year is $30 x 4 = 120.
Therefore, the total money he earns for his oranges and apples is $300 + $120 = $420.
