Rogelio has car insurance that he must pay four times a year. if each payment is $144, how much money should he set aside each month to cover his car insurance?

He should set aside at least $48 each month.

48$
Explanation: since he pays his car insurance 4 times a year and each payment is 144$ that means he pays 144$ every 3 months since 12 divided by 4 equals 3
So 144 divided by 3 is 48 so if he puts aside 48 dollars each month he will have 144$ every 3 month to pay his car insurance
