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?
##Solution## Gold = <<141=141>>141
Silver = 141 * 2 = <<141*2=282>>282
141 + 282 + 150 = <<141+282+150=573>>573
There are 573 gold, silver, and black balloons in total.
#### 573
