To correct the logic for most statements you'll want to test the value of money AND if today is Friday. Currently the statements test the value of money OR if today is Friday. So for example:

if ( money >= 100 || today === 'Friday' ) {

becomes this:

if ( money >= 100 && today === 'Friday' ) {

Then you have this statement which is the condition we want to execute:

else if ( today !== 'Friday' )

It doesn't make sense with the alert "It's Friday, but I don't have enough money to go out" because it checks if today is not Friday. You only need to change this to check if today is Friday - the money variable shouldn't be added to the statement. 'money' has already been checked by the previous conditions.

var money = 9; var today = 'Friday'

} else if ( money >= 50 || today === 'Friday' ) { alert("Time for a movie and dinner");
} else if ( money > 10 || today === 'Friday' ) { alert("Time for a movie");
} else if ( today === 'Friday' ) { alert("It's Friday, but I don't have enough money to go out");
} else { alert("This isn't Friday. I need to stay home."); }

These statements:

} else if ( money >= 50 || today === 'Friday' ) { alert("Time for a movie and dinner");
} else if ( money > 10 || today === 'Friday' ) { alert("Time for a movie");

need to be changed to use && operators also
