Answer:
$1,720
Step-by-step explanation:
Total annual premium for both Karen and Mike = $400 + $600 = $1,000
If they insured both cars with the same company, they would save 15% on the annual premiums -> the annual saving = 15% * $1,000 = $150
We use formula FV to calculate the future value of annual payment:
= FV(rate, number of payment, - payment) = FV(3%,10,-150) = $1,720
