Calculate the finance charge and new balance using the previous balance method. Previous balance = $179.32 Annual rate = 16% Fin
garik1379 [7]
Annual Rate = 16% = 16/100 = 0.16
Monthly Rate = (annual rate)/12
Monthly Rate = (0.16)/12
Monthly Rate = 0.01333 ... this is approximate

Finance Charge = (Monthly Rate)*(Previous Balance)
Finance Charge = (0.01333)*(179.32)
Finance Charge = 2.3903356
Finance Charge = 2.39

The purchases and payments do not factor in the finance charge since they are made during this current billing cycle. The previous balance method only looks at the balance at the end of the previous cycle. 

Once the finance charge is calculated, we add on the new purchases and the finance charge to the old balance. We also subtract off the payments/credits. Doing all this calculates the new balance for this billing cycle. 

New Balance = (Old balance) + (Purchases) + (Finance Charge) - (Payment)
New Balance = 179.32 + 117.42 + 2.39 - 85
New Balance = 214.13

In summary, 
Finance Charge = $2.39
New Balance = $214.13

The formula f 5280m can be used to convert a measurement of f feet to an equivalent measurement of m miles. If an airplane flies
konstantin123 [22]
Just to help you, that formula is saying that 1 mile is equivalent to 5280 feet, i.e. the number of feet is equal to 5280 * number of miles.

So, you know the number of feet = 21,120 and have to convert that into the equivalent number of miles:

f = 5280m => m = f / 5280

m = 21,120 / 5280 = 4 miles

Answer: 4 miles
