Brian pays
\[\$600\] every six months for his car insurance. He just paid his bill for this year, but wants to budget for his next payment and save an equal amount each month. He has
\[5\] months until his insurance is due again.
How much money will Brian need to save each month?
Brian wants to save an equal amount each month for his car insurance payment. Since he has 5 months until his insurance is due again, he needs to save the same amount each month for a total of $600.
To find out how much money Brian needs to save each month, we divide the total amount he needs to save by the number of months:
\[600 \div 5 = 120.\]
Therefore, Brian needs to save $\$120$ each month for his car insurance payment. Answer: \boxed{120}.
