Answer:
$18,000
Step-by-step explanation:
It is given that the interest amount $6,300
We will calculate the principal amount.
So we use the formula
I = prt
P = Principal amount
r = rate of interest 7% ( 0.07 )
t = time in years 60 months ( years )
6,300 = P × 0.07 ×
6,300 = P × 0.07 × 5
6,300 = 0.35P
= P
P = $18000
The original loan amount was $18,000.

Answer:
B. 1.4 feet
Step-by-step explanation:
Let, the amount of increase be 'x' ft.
Since, the length and width of the canvas are 4 ft and 3 ft respectively.
Thus, area of the canvas, = length × breadth = 4 × 3 = 12 ft²
Since, the area of display model is twice the area of the canvas. We have,
= 2 ×
i.e. = 2 × 12
i.e. = 24 ft².
As, the length and width of the canvas are increased by 'x'.
The, length and width of the display model are (x+4) ft and (x+3) ft.
So, we get,
= length × breadth = (x+4) × (x+3) =
Since, = 24 ft²
i.e. = 24
i.e.
Solving the quadratic equation, we get,
i.e. x = -8.4 and x= 1.4
Since, the value of x cannot be negative.
Thus, x = 1.4 feet.
Answer: Lela's original score was 16.
Step-by-step explanation:
Alright lets get started.
Suppose Lela score was L.
Suppose Pepe score was P.
The ratio of Lela’s game score to Pepe's score is
So the equation will be
Cross multiplying
.................equation 1
Then Lela completes a quest and scores 12 bonus points. The new ratio becomes
Cross multiplying
Plugging value of P from equation 1
Hence the score of Leela originally was 16. Answer
