Count the total colors of beads
42+28+12+18=100
Next, calculate the sum of the yellow and green beads
42+28=70
To determine the count of beads that are neither yellow nor green, subtract from the total
100-70=30
The first answer thus is 30/100 -> 3/10 -> 30%
Now, tally the red and green beads
28+18=46
Thus, the next answer is
46/100 -> 23/50 -> 46%
The correct answer is that you start with no refills, paying $2 for the first drink, and when you receive a refill, you pay an additional $1, totaling $3.
By solving the equation -x+8+3x=x-6, we rearrange it to 2x+8=x-6. This leads to the simplification 2x-x=-6-8, yielding x=-14. The correct answer is letter B.
