Mitch earns 5 x $3 = $<<5*3=15>>15 every weekday.
So, she earns $15 x 5 = $<<15*5=75>>75 from Monday to Friday.
And she earns $3 x 2 = $<<3*2=6>>6 per hour every weekend.
Hence, the total amount she earns every weekend is $6 x 3= $<<6*3=18>>18.
So, she earns $18 x 2 = $<<18*2=36>>36 every Saturday and Sunday.
Therefore, the total amount she earns every week is $75 + $36= $<<75+36=111>>111.
