Q. Ivy is downloading a computer program from the Internet. After 88 minutes, the computer program is 35% 35 \% downloaded. If the computer program continues to download at the current rate, about how much longer will it take for Ivy's computer to finish downloading the program?\newlineChoose 11 answer:\newline(A) 1212 minutes\newline(B) 15 \mathbf{1 5} minutes\newline(C) 1818 minutes\newline(D) 2323 minutes
  1. Calculate Percentage Remaining: Determine the percentage of the program that is still needed to be downloaded.\newlineSince 35%35\% of the program has been downloaded in 88 minutes, the remaining percentage to be downloaded is 100%35%=65%100\% - 35\% = 65\%.
  2. Calculate Rate of Download: Calculate the rate of download per minute.\newlineTo find the rate, we divide the percentage downloaded by the time taken so far.\newlineRate = 35% downloaded8 minutes=4.375%\frac{35\% \text{ downloaded}}{8 \text{ minutes}} = 4.375\% per minute.
  3. Calculate Time Needed: Calculate the time needed to download the remaining 65%65\% at the rate of 4.375%4.375\% per minute.\newlineTime needed = Remaining percentage to download / Rate of download per minute\newlineTime needed = 65%/4.375%65\% / 4.375\% per minute 14.857\approx 14.857 minutes.
  4. Round to Nearest Whole Number: Round the time to the nearest whole number since the answer choices are in whole minutes.\newlineThe time needed is approximately 1515 minutes when rounded to the nearest whole number.
