There were s students at a summer camp in 2010. in 2011, there were half as many students as the previous year. in 2012, there were 54 fewer students than in 2010. what expression would represent the total number of students at the summer camp for all three years?

I’m still confused on how to work the percentages

Jenny invests $2,000 at an interest rate of 5%. the amount of money, me, in jenny's account after tyears can be represented using the equation ma-2000(1.05). if jenny would have invested the same amount of money at the same interest rate four years ago, the equation representing the amount of money mo. in her account would be represented using the equation! mg = 2000(105)*** which of the following is equivalent to mp? 2000(105) om- 1.05 2000(1.05) mo 1059 mp-2000(1.05) (105) mp - 2000(1.05) + (1.05)

Simplify the expression 8h - 57-3m by adding or subtracting the like term
