Alex deposits $250 at the end of each month into an account that earns 4% interest compounded monthly. Determine the value of Alex’s account after 10 years. State you answer to the nearest $1

look up sinking fund formula

r = .04/12 rate per month
n = 10*12 = 120 months

250 = P /[ (1+r)n -1]/r
so
P = 250 [ (1+r)n -1]/r
