<human>:  John gets his pool cleaned every 3 days. It cost $150 each time and he gives the guy a 10% tip each time he comes to clean. Then twice a month he needs to use $200 of chemicals. How much does his pool cost a month?
<bot>: How many times does John get his pool cleaned in a month? ** He gets his pool cleaned 30/3=<<30/3=10>>10 times a month
How much does John tip each time he gets his pool cleaned? ** Each time he gets it cleaned he tips 150*.1=$<<150*.1=15>>15
How much does John pay each time he gets his pool cleaned? ** So he pays 150+15=$<<150+15=165>>165
How much does John pay in total for cleaning? ** So he pays 165*10=$<<165*10=1650>>1650 a month on cleaning
How much do the chemicals cost? ** The chemicals cost 200*2=$<<200*2=400>>400
How much does John pay in total? ** So in total, he pays 1650+400=$<<1650+400=2050>>2050
