Step-by-step explanation:
100(1.35(0.8)p-p)/p=8%
Since this is positive the dealer makes an 8% profit.
Hey. Let me help you on this one.
In this problem, we will be needing to calculate values for two different banks with different interest rates. We will need to add both of these values together to find out the total amount of money Gia has. We will also need to find the percentage increase by using the percentage decimal form.
First, let's form two expressions which we can later solve. First account earns an annual 3.4% interest, and the second one earns half of that.

Now that we know the interest rate for both banks (first, and second), we can form an expression for all of them. Before we do this; however, let's find the percentage increase for the banks.
First bank:

Second bank:

Let's form expressions for the banks, now. In order for us to find a certain percentage, we can take the percent in the decimal form, and move the decimal point two spaces to the left.
First bank:

Second bank:

Now, let's add the values together.

Done. We now have our answer. I will be attaching the image that will help you understand what has been done to solve this problem. It should help you on your studies.
Answer: Gia has earned $102 in four years.
Letting x be the side-length of the square, the new rectangle has length x and width x+3. Thus, the area is (x)(x+3)=x^2+3x. This is not an answer choice.
Answer:
(a)18.85 Cubic Inches
(b)The box with dimensions of 4 in. x 3in. x 2 in.
Step-by-step explanation:
<u>Part A</u>
<u>Volume of the 12 Containers</u>
Height =2 Inches
Diameter=1 Inch
Radius=Diameter/2=1/2=0.5 Inch
Volume of a cylinder
Volume of the 12 Containers

<u>Part B</u>
To determine the container which should be used, we first determine the volume of the available boxes.
<u>Volume of the boxes</u>
Volume of box with dimension 3 in. x 2 in. x 5 in.=3X2X5=30 Cubic Inches
Volume of box with dimension 4 in. x 3in. x 2 in.=4X3X2=24 Cubic Inches
Volume of box with dimension 5 in. x 6 in. x 5 in.=5X6X5=150 Cubic Inches
Volume of box with dimension 3 in. x 2 in. x 3 in. =3X2X3=18 Cubic Inches
The box that should be used with the least amount of wasted space is he box with volume 24 Cubic inches. i.e. box with dimensions 4 in. x 3in. x 2 in.
This is because the volume of the box(18 cubic inches) with dimension 3 in. x 2 in. x 3 in. is less than what is required.
