<human>:  Mike and Ted planted tomatoes. In the morning, Mike planted 50 tomato seeds while Ted planted twice as much as Mike. In the afternoon, Mike planted 60 tomato seeds while Ted planted 20 fewer tomato seeds than Mike. How many tomato seeds did they plant altogether?
<bot>: How many tomato seeds did Ted plant? ** Ted planted 2 x 50 = <<2*50=100>>100 tomato seeds.
How many tomato seeds did Mike and Ted plant in the morning? ** So, Mike and Ted planted 50 + 100 = <<50+100=150>>150 tomato seeds in the morning.
How many tomato seeds did Ted plant in the afternoon? ** In the afternoon, Ted planted 60 - 20 = <<60-20=40>>40 seeds.
How many tomato seeds did Mike and Ted plant in the afternoon? ** Thus, Mike and Ted planted 60 + 40 = <<60+40=100>>100 tomato seeds in the afternoon.
How many tomato seeds did Mike and Ted plant altogether? ** Therefore, they planted 150 + 100 = <<150+100=250>>250 tomato seed altogether.
