The balance on a credit card, that charges a 15.5%APR interest rate, over a 1 month period is given inthe following table:Days 1
Karo-lina-s [1.5K]

First step is to get the average daily balance.

Take the sum of each day's balances.

If a payment has been made, the sign will be negative.

From Days 1 - 5 :

Day 1 = $200

Day 2 = $200

...

Day 5 = $200

That's $200 x 5 days = $1000

From Days 6 - 20 :

Day 6 = $350

Day 7 = $350

...

Days 20 = $350

That's $350 x 15 days = $5250

From Days 21 - 30 :

Day 21 = $150

Day 22 = $150

...

Day 30 = $150

That's $150 x 10 days = $1500

A total of :

$1000 + $5250 + $1500 = $7750

Now divide this total to the number of days to get the ADB or Average Daily Balance.

\text{ADB}=\frac{7750}{30}=258.33

Next Step is to calculate for the finance charge using the formula :

\text{Charge}=\text{ADB}\times r\times d

where ADB is the average daily balance

r is the interest rate per day

d is the number of days or period given

From the problem, APR is 15.5%, it means that we need to divide the APR by 365 days.

So r = 0.155/365 = 0.000425

And we have d = 30 days

The charge will be :

Charge = 258.33 x 0.000425 x 30 = $3.29

The answer is $3.29

Jason purchased 12 shirts for the members of a school club. Each shirt cost $5.50. Jason
Alex Ar [27]

Answer:

52 dollars and 47 cents, or 52.47

Step-by-step explanation:

First, multiply 12 and 5.50, then you should get 66.00. Then, take the 25% discount, and divide it by a hundred, you should get 0.25, now multiply 0.25 and 66.00. You should get 16.50, thats your discount, so subtract 16.50 from 66.00, you should get 49.50. Now for the sales tax, divide 6.0 by 100, you should get 0.06. Now multiply 0.06 and 49.50, you should get 2.97, thats your tax, add it to 49.50, and you get 52.47 so BOOM, thats your answer, your welcome
