Another bank offers a different savings rate. If an account with $400 earns interest of $6, how much interest is earned by an account with $1800?

  • Algebra -

    Just use a simple ratio equation

    x/6 = 1800/400
    x = 27

    or

    rate for the account = 6/400 = .015

    so for the $1800 , interest = .015(1800) = 27
