Mathematics help please?

A video store rents new release movies for $4 and favorites for $2.25. One day the number of new release movies rented was twice the number of favorites. If the total income from those rentals was $666.25, how many movies of each kind were rented?

new releases

favorites

    Write two simultaneous equations and substitute to solve

    4n + 2.25 f = 666.25 (new releases n, favorites f), but also

    n = 2f

    8f + 2.25 f = 10.25f = 666.25

    f = 65, n = 130

    x = favourites

    2x = new

    4*(2x)+2.25x = 10.25x = 666.25

    x = 65 favoutites

    new releases = 130

    It’s a lie. Video stores do not exist anymore
