Travis has lost or broken 12 + 15 = <<12+15=27>>27 bowls.
Travis will need to pay the store 27 x $4 = $<<27*4=108>>108 dollars.
Travis has safely taken 638 - 27 = <<638-27=611>>611 bowls.
For this, he will be paid 611 x $3 = $<<611*3=1833>>1833 dollars
In total Travis will be paid $1833 + $100 = $<<1833+100=1933>>1933 dollars.
Since Travis has to pay the home goods 108 for the broken and lost bowls, he will end up with $1933-$108 = $1825.
