Answer:
[tex]\$3935[/tex]
Step-by-step explanation:
Total bills to be paid in 1 month
[tex]575+230+170+120+550+500=\$2145[/tex]
The bills for 3 months is
[tex]2145\times 3=\$6435[/tex]
Amount of money in the bank account = [tex]\$3000[/tex]
To pay the bills she needs
[tex]6435-3000=\$3435[/tex] more.
She also needs to have $500 dollars after the bills are paid so
[tex]3435+500=\$3935[/tex]
Hence, Mrs. Pedersen needs to deposit [tex]\$3935[/tex] in her bank account.
