My question is: A gumball machine has red, green, and blue gumballs. The machine has half as many blue gumballs as red gumballs. For each blue gumball, the machine has 4 times as many green gumballs. If the machine has 16 red gumballs how many gumballs are in the machine? Your thoughts:
There are 16 / 2 = 8 blue gumballs. There are 8 * 4 = 32 green gumballs. There are 16 + 32 + 8 = 56 total gumballs. The final answer: 56.
