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?
Let's think step by step.
2050
He gets his pool cleaned 30 / 3 = 10 times a month.

Each time he gets it cleaned he tips 150 *.

1 = $15.

So he pays 150 + 15 = $165.

So he pays 165 * 10 = $1650 a month on cleaning.

The chemicals cost 200 * 2 = $400.

So in total, he pays 1650 + 400 = $2050.

.

So, the answer is 2050
