Answer:
Area = 84 in²
Step-by-step explanation:
In order to find the area of the rectangle, you need to first set up an equation to find the length based on the information already given in the problem. Since the perimeter = 40 and the formula to find perimeter of a rectangle is: P = 2W + 2L, where W = width and L=Length, we can solve for 'L' by putting in the values given:
P = 2W + 2L or 40 = 2W + 2(3W - 4)
The length of the rectangle is '4 less than 3 times the width'. This can be written as the expression '3W - 4'.
Distribute: 40 = 2W + 2(3W - 4) or 40 = 2W + 6W - 8
Combine like terms: 40 = 8W - 8
Add '8' to both sides: 40 + 8 = 8W - 8 + 8 or 48 = 8W
Divide both sides by '8': 48/8 = 8W/8 or 6 = W
Solve for L: 3W - 4 or 3(6) - 4 = 18 - 4 = 14
Since L=14 and W = 6, we can solve for Area using the formula: A = LxW or A = (14)(16) = 84in².
For example, if your fraction was 1 1/2, you would graph it on the x axis halfway between 1 and 2
Cuz she divided 23 and 8 and got 21 then she added 3+3= 6 + 4= 10
The monthly finance charge when the previous balance method is used is $245.83
<h3>How to calculate the amount?</h3>
The finance charge using the previous balance method will be:
= 3000 × 15 × 1/(12 × 100) + 2500/12
= 3000 × 15 × 1/1200 + 208.33
= $245.83
The charge when the adjusted balance method is used will be:
= $3000 - $2500
= $500
The charge when the average daily balance is used will be:
= 3000 × 15% × (1/12)
= 3000 × 0.15 × (1/12)
= $37.50
