Step-by-step explanation:

1) Given :  Previous balance = $104.15

Annual rate = 14%

New purchases = $31.23

Payments/credits = $42.50

To find : What is the finance charge and new balance?  

Solution :  

First we find the unpaid balance,

Unpaid balance = Previous balance - Payments

                          = $104.15 - $42.50

Unpaid balance  = $61.65

We have given rate of interest= 14%=0.14

Finance charge = Finance rate × Unpaid balance

Finance charge =

Finance charge = $0.71925

New balance =  Unpaid balance + finance charge + new transaction

New balance =  $61.65 +$0.71925+ $31.23

New balance =$93.59925

2) Given :  Previous balance = $224.12

Annual rate = 16%

New purchases = $15.11

Payments/credits = $124.35

To find : What is the finance charge and new balance?  

Solution :  

First we find the unpaid balance,

Unpaid balance = Previous balance - Payments

                          = $224.12 - $124.35

Unpaid balance  = $99.77

We have given rate of interest= 16% =0.16

Finance charge = Finance rate × Unpaid balance

Finance charge =

Finance charge = $1.33026

New balance =  Unpaid balance + finance charge + new transaction

New balance =  $99.77 +$1.33026+ $15.11

New balance =$116.21026

3) Given :  Previous balance = $250.25

Annual rate =20%

New purchases = $0.00

Payments/credits = $51.44

To find : What is the finance charge and new balance?  

Solution :  

First we find the unpaid balance,

Unpaid balance = Previous balance - Payments

                          = $250.25 - $51.44

Unpaid balance  = $198.81

We have given rate of interest=20% =0.2

Finance charge = Finance rate × Unpaid balance

Finance charge =

Finance charge = $3.3135

New balance =  Unpaid balance + finance charge + new transaction

New balance =  $198.81 +$3.3135+ $0.00

New balance = $202.1235

i just took the test, the correct answer is .. 31.5 in.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
