Four friends ordered four pizzas for a total of 64 dollars. If two of the pizzas cost 30 dollars, how much did each of the other two pizzas cost if they cost the same amount?
assistant
How much did the other two pizzas cost in total? ** The other two pizzas cost 64-30 = <<64-30=34>>34 dollars.
How much did each of the other two pizzas cost? ** Each of the other two pizzas cost 34/2 = <<34/2=17>>17 dollars each.
