<human>:  Mabel planted 4 tomato plants. One tomato plant bore 8 tomatoes and another bore 4 more tomatoes than the first. The two remaining plants each bore three times the number of tomatoes as the first two plants combined. How many tomatoes does Mabel have?
<bot>: How many tomatoes does the second plant bear? ** The second tomato plant bore 8 + 4 = <<8+4=12>>12 fruit.
How many tomatoes do the first two plants bear? ** The first two plants bore 8 + 12 = <<8+12=20>>20 fruit combined.
How many tomatoes do the other two plants bear? ** Each of the other two plants bore 20 x 3 = <<20*3=60>>60 fruit.
How many tomatoes does Mabel have? ** Mabel has 8 + 12 + 60 + 60 = <<8+12+60+60=140>>140 tomatoes
