Why is the percent increase from 45 to 75 not equal to the percent decrease from 75 to 45? select three. the amount of change is different for the percent increase and the percent decrease. the ratio of the percent increase is not the same as the percent decrease. the ratio for the percent increase has a smaller denominator than the percent decrease. the ratio for the percent increase has a different numerator than the percent decrease. the ratio of the percent increase is the same as the percent decrease. the original amount for the percent increase is different from the original amount for the percent decrease.

Step-by-step explanation:

From 45 to 75:

We could calculate this using the rule of three. If 45 is 100%, 75 what percentage would be?

From 75 to 45:

We do the same process, but in the opposite way. If 75 represents 100%, 45 what percentage would be?

So, comparing both process we conclude that, both ratios are not the same, we judge this by watching is fraction, and each result. Also, the ratio for the percentage increase has lower denominator (45) than the percentage decrease (75). Lastly, the original amounts in each case is different, the increased started from 45, and the decreased started from 75.

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
