Hi, I need help with this Math and Stats problem, please. Thank you!
One of your friends missed class, and you are helping them get caught up. Which of the following is the best explanation for the answer for the meaning of 2.45x? a. If you convert 2.45 to a percent, you get 245%. So multiplying by 2.45 is an increase of 245%. b. 2.45x increases by 245% because x + 1.45x = 2.45x c. 2.45x is 1x + 1.45x, where 1x is 100% of x and 1.45x is 145% of x. So you are adding 100% + 145%, which is an increase of 145% over the original 100% d. Think of 2.45x as a percent, so when you multiply by 2.45% you are actually decreasing x by 97.55%.
