Last year there were 400 students in 7th grade. The number this year increased by 15%. How many stundents are in 7th grade this year?

No one answered when i posted it so i posted it again i will give 20 points and brainliest the club will base its decision about whether to increase the budget for the indoor rock climbing facility on the analysis of its usage. the decision to increase the budget will depend on whether members are using the indoor facility at least two times a week. use the best measure of center for both data sets to determine whether the club should increase the budget. assume there are four weeks in a month. if you think the data is inconclusive, explain why.
