Answer:
The percent off on the sale price is 30%.
Step-by-step explanation:
Marked up price = $64.99
marked down Price = $45.49
Let us assume the off percentage = k%
Now, the Amount off on the sale = Marked up price - Marked down price
= $64.99 - $45.49 = $19.5
⇒ k% off on Marked up Price $64.99 = $19.5
or,
or, k = 30%
Hence, the percent off on the sale price is 30%
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.
