Aight so first you need to isolate the y. Simply add 8 to both sides and now you have 1/4y = 33. Now divide both sides by 1/4 (which is the same by multiplying by 4) and you get 132
The sample size can be calculated by the following formula:
where s is the sample size, z is the z-score of the confidence level, p is the decimal form of the percentage who picked a certain choice in the poll, and E is the margin of error expressed as a decimal.
We first find the margin of error in the original sample size of 270.
Since the new sample had 3 times the margin of error of the first poll, we will use 3(0.038) or 0.114 as the margin of error of the new sample. We then compute for the sample size using the same formula.
