<human>:  There are 141 gold balloons and twice as many silver balloons. If the gold and silver balloons were added to 150 black balloons, how many balloons are there in total?
<bot>: How many gold balloons are there? ** Gold = <<141=141>>141
How many silver balloons are there? ** Silver = 141 * 2 = <<141*2=282>>282
How many balloons are there in total? ** 141 + 282 + 150 = <<141+282+150=573>>573
How many balloons are there in total? ** There are 573 gold, silver, and black balloons in total.
