Alexandra romar has a previous balance at porter pharmacy of $68.42. she had payments and credits of $18.25. the monthly finance charge is 1.85% of the unpaid balance. after the finance charge was calculated, she made $34.00 in new purchases. what is her new balance?

Her new balance is $85.10.

Step-by-step explanation:

Alexandra Romar has a previous balance at Porter Pharmacy = $68.42

She had payments and credits = $18.25

Now the unpaid balance = 68.42 - 18.25 = $50.17

The monthly finance charge on unpaid balance = 1.85% × 50.17

                                                                       = × 50.17

                                                                        = 0.928145 ≈ $0.93

So the balance with finance charge =    50.17 + 0.93 = 51.10

She made a new purchase = $34.00

Her new balance = 51.10 + 34.00 = $85.10

Her new balance is $85.10.
