How much money does Shelly have in ten $10 bills? ** Shelly's ten $10 bills amount to 10 x $10 = $<<10*10=100>>100.
How many $5 bills does Shelly have? ** She has 10 - 4 = <<10-4=6>>6 $5 bills.
How much money does Shelly have in six $5 bills? ** The 6 $5 bills amount to 6 x $5 = $<<6*5=30>>30.
How much money does Shelly have in all? ** Thus, Shelly has $100 + $30 = $<<100+30=130>>130 in all.
