What is the "base" given the part of $12,495 and a percent decrease of 30%??? Topic is "finding the base". Please help! I already did the quiz but it doesn't show me the answers, all I know is I got it wrong but idk how to solve it because it doesn't let me check the answers.

The frequency table shows the results of a survey asking people how many hours they spend online per week. on a piece of paper, draw a histogram to represent the data. then determine which answer choice matches the histogram you drew. in order here is the.. hours online: 0-3, 4-7, 8-11, 12-15, and 16-19. frequency: 5, 8, 10, 8, 7 answer for the question is in the picture! : )
