Final answer:
John and Jen's combined monthly auto insurance premium for 2022 was $177.50, calculated by adding their annual premiums and dividing by 12.
Step-by-step explanation:
The question involves calculating the total monthly auto insurance premium for John and Jen who purchased their policies for an entire year in 2022. The total annual premium for John is $1180 and for Jen is $950. The combined annual premium for both is calculated by adding the two amounts: $1180 + $950 = $2130. To find their total monthly premium, we divide the annual combined premium by 12 (the number of months in a year): $2130 / 12 = $177.50. Therefore, their total monthly premium is $177.50.
