Answer:
$4080
Step-by-step explanation:
We have the amount she will pay back, but first, we need to find the Interest accrued.
Simple Interest is given as:

where P = principal
R = rate
T = time taken (in years)
Therefore, the interest on $3,000 at 9% simple interest for 4 years is:

I = $1080
Therefore, the amount she will pay back is:
$3000 + $1080 = $4080
If there are no notebooks purchased, then Eula may buy 5 binders. If no binders are bought, then Eula may buy 10 notebooks. If 7 notebooks are purchased, then one binder may be purchased; this will also cause Eula to have $2 extra (maybe for tax).
Answer:
(5.4k+7.9m+8.1n) centimeters
Step-by-step explanation:
Given the side length of a triangle;
S1 = (1.3k+3.5m) cm
S2 = (4.1k-1.6n) cm
S3 = (9.7n+4.4m) cm
Perimeter of the triangle = S1+S2 + S3
Perimeter of the triangle = (1.3k+3.5m) + (4.1k-1.6n) + (9.7n+4.4m)
Collect the like terms;
Perimeter of the triangle = 1.3k+4.1k+3.5m+4.4m-1.6n+9.7n
Perimeter of the triangle = 5.4k+7.9m+8.1n
Hence the expression that represents the perimeter of the triangle is (5.4k+7.9m+8.1n) centimeters
Answer:
<u>Part A: Cost for the flooring is $ 4,231.50</u>
<u>Part B: Cost for the flooring is $ 5,531.50</u>
Step-by-step explanation:
Step 1:
Let's calculate the area of the living/dining room, this way:
Area = 26 * 25
Area = 650 ft²
Step 2:
Let's calculate the cost of the flooring if Nancy installs it:
Cost = $ 6.51 * Area of the living/dining room
Cost = 6.51 * 650
<u>Cost = $ 4,231.50</u>
Step 3:
Let's calculate the cost of the flooring if the flooring company installs it:
Cost = $ 8.51 * Area of the living/dining room
Cost = 8.51 * 650
<u>Cost = $ 5,531.50</u>
