Let, the original amount = x
First discount = x * 0.20 = 0.20x
Amount after first discount = x - 0.20x = 0.80x
Second discount = 0.80x * 0.15 = 0.12x
Amount after second discount = 0.80x - 0.12x = 0.68x
Difference would be: x-0.68x = 0.32x
So, Your Answer would be 32%
Hope this helps!
Answer:
B and C
Step-by-step explanation:
The reason is on the picture.
Answer:
In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

The given pair of lines are not perpendicular.
<h3>What is a line?</h3>
The line is a curve showing the shortest distance between 2 points.
5x - 5y = -2 - - - - - (1)
Transform the equation into standard form,
5x + 2 = 5y
y = 5x /5 + 2/5
y = x + 2/5
The slope of equation 1 is
and intercept c = 2 / 5
Similarly
x + 2y = 4 - - - - - - - -(2)
Transform it into standard form
y = -x/2 + 4 /2
y = -x / 2 + 2
Slope of the equation 2
= -1 / 2 and intercept c = 2
Slope of line 1 * slope of line 2 = 1 * -1/2 = -1/2
Since the lines are not perpendicular because the pair of lines does not satisfy the property of perpendicular lines i.e

Thus, the given pair of lines are not perpendicular.
