Enrico deposited \$2000$2000dollar sign, 2000 in a savings account. Each month he will deposit an additional \$25$25dollar sign, 25. Which kind of function best models the relationship between time and the total amount in the savings account?

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
