Original price of the item = $14.95
Price after discount = $13.79
Discount offered = original price - price after discount = 14.95- 13.79 = $1.16
Now let us find the percentage of discount offered.
Percentage discount is given by the formula:
Where MP= Marked price= original price
SP= selling price= price after discount
Percentage discount = 7.759 %

Given parameters:
Recommend wheelchari ramp slope =
Rise of the new wheel chair ramp = 22 inches
Horizontal length = 24feet
Unknown:
Is the ramp steeper than the recommended = ?
Slope is the ratio of rise to the horizontal distance covered
Mathematically;
Slope =
Slope of the wheel chair ramp;
covert 24 feet to inches;
1 foot = 12 inches
24 feet = 24 x `12 = 288inches
Slope = =
The two slopes being compared are;
and
The steeper of the first one 1/12. It has a higher slope compared to the second one.
