Final answer:
To find the number of gummy bears in the bag, set up the equation 0.2x = 12, where x is the total number of gummy bears in the bag. Solve for x to find that there are 60 gummy bears in the bag.
Step-by-step explanation:
To find the number of gummy bears in the bag, we can use the information given. We know that 20% of the gummy bears are blue, and there are 12 blue gummy bears in the bag. So we can set up the equation: 0.2x = 12, where x is the total number of gummy bears in the bag. To solve for x, we divide both sides of the equation by 0.2: x = 12 / 0.2 = 60.
