You invest $1000 dollars in an account at 2.5% per year simple interest. how much will you have in the account at the beginning of the 4th year. round your answer to the nearest whole dollar

I = PRT

P = 1000
R = 2.5% -- change to a decimal = .025
T = 3

now we sub I = PRT
I = (1000)(.025)(3)
I = 75
 so at the end of 3 years, there will be : 1000 + 75 = $ 1075 in the account

Hope this helps!!
