First figure out how much the first babysitter costs by multiplying her hourly rate by the number of hours she works: $16/hour * 6 hours = $<<16*6=96>>96

Then use the same method to figure out how much the second babysitter charges before any screaming: $12/hour * 6 hours = $<<12*6=72>>72

Then figure out how much the babysitter charges for two screams: 2 screams * $3/scream = $<<2*3=6>>6

Finally, subtract the second babysitter's two charges from the first babysitter's total charge to find the difference: $96 - $72 - $6 = $<<96-72-6=18>>18

Milly's babysitter charges $16/hour. Milly is considering switching to a new babysitter who charges $12/hour, but also charges an extra $3 for each time the kids scream at her. If Milly usually hires the babysitter for 6 hours, and her kids usually scream twice per babysitting gig, how much less will the new babysitter cost?
