Answer: 31.25

Step-by-step explanation:

Okie dokie, so if something is marked up by 20% it means, it is 120% the original number right?

So we can convert 120% into 1.2 to make solving this problem easier. :)

So if we want to find the original number, all we have to do is divide 37.5 by 1.2.

This gets us 31.25.

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

What is the area of this figure?
Alexxandr [17]

Answer:

The area of the figure is equal to 35\ cm^{2}

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of the figure is equal to the area of a square plus the area of a triangle

<u>Find the area of the square</u>

The area of square is equal to

A=b^{2} =5^{2}=25\ cm^{2}

<u>Find the area of the triangle</u>

The area of the triangle is equal to

A=(1/2)bh=(1/2)(5)(4)=10\ cm^{2}

therefore

The area of the figure is equal to

25\ cm^{2}+10\ cm^{2}=35\ cm^{2}

The perimeter of a rectangle is 84 feet. the length is two feet greater than 3 times the width. Find the length and width. Draw
Kipish [7]
The formula for a rectangle's perimeter is

P = 2l + 2w

We know the length is 2 ft greater than thrice the width, so 2l becomes:

3w + 2ft + 3w + 2ft

Substitute.

P = 3w + 2ft + 3w + 2ft + 2w

Add like terms.

P = 8w + 4ft

Substitute P.

84 ft = 8w + 4ft

Subtract 4 ft from both sides to eliminate. (Property of equality)

84 ft - 4ft = 8w + 4ft - 4ft
80 ft = 8w

Divide 8 on both sides to isolate w.

80 ft / 8 = 8w / 8

10 ft = w

We have the value of w, now look for the l which we know is 2 feet more than thrice the value of w.

l = 10 ft × 3 + 2 ft
l = 30 ft + 2 ft
l = 32 ft

Therefore, the length and the width of the rectangle is 10 ft (w) and 32 ft (l).

Check:
84 ft = (2) (10 ft) + (2) (32 ft)
84 ft = 20 ft + 64 ft
84 ft = 84 ft ✔
