Answer:
choices A and F are part of Leo's system of equations
Step-by-step explanation:
The formula for the amount in an account compounded annually is ...
A = P(1 +r)^t
For the given amounts and variables, that is ...
y = 500(1.025)^x . . . . matches F
__
The formula for the amount in an account compounded continuously is ...
A = P·e^(rt)
With given values, this is ...
y = 400e^(0.02x) . . . . matches A
