Answer:
C : $58.36
Step-by-step explanation:
Given:
A store holiday sale has an item marked down by $10.
Discount on new price = 25%
Final price was $36.27.
Question asked:
what was the original ?
Solution:
Let original price =
New price =
Original price - marked down amount - discount amount = $36.27
Adding both side by 7.5
Dividing both side by 0.75
Therefore, the original price was $58.36
So I went ahead and divided up the figure so that you would understand what I'm going to tell you. Let's start with the red rectangle.
The distance from point R to point I is 6 units and the distance from Point R to point S is 5 units. 6*5 = 30 so that red rectangle has an area of 30 units
Now let's calculate triangle AVI. Area of a triangle is Base * Height. The base is 1 and the height is 5 which means the area of triangle AVI is 5.
Next, triangle ALT. From Point A to point L is 4 unit. From Point L to point T is 3 units. 4*3 is 12. So triangle ALT has an area of 12.
Triangle TSI. From Point T to point L is 3 units. From Point L to X is 2. Triangle TSI has an area of 6.
Now we add all of them up. 30+5+12+6 = 53. In total, RSTUV has an area of 53
