Jon's water heater is old and will need replacement in the future. A new water heater costs
\[\$900\]. Jon would like to replace it in a year, but wants to start saving for it now. He plans on saving equal amounts every month.
How much money will Jon need to save each month?
\[\$\]
per month
Jon wants to save for the water heater over the course of 1 year, or 12 months.
To determine how much money Jon needs to save each month, we divide the total cost of the water heater by the number of months: $900 / 12 months = $<<900/12=75>>75 per month. Answer: \boxed{75}.
