The total value of the account is based on the function f(x) = q • 1.025x, where x represents the number of years the money has been in the account. if no deposits or withdrawals have been made since the initial deposit, which equation represents the total value of the account?

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
