Answer:
C
Step-by-step explanation:
5a - 3b^2 - a + b - 5 + 8a^2
8a^2 - 3b^2 + 4a + b - 5
Cost Price = $60
Markup = 25% x $60 = 0.25 x 60 = $15
Sales Price after markup = $60 + $15 = $75
Discount = 20% x $75 = 0.2 x 75 = $15
Sales Price after discount = $75 - $15 = $60
Sales Tax = 6% x $60 = 0.06 x 60 = $3.60
Sales Price with Discount after tax = $60 + $3.60 = $63.60
Answer: $63.60

The slope of a line parallel to the line whose equation is 6x + y = -3 is: -6.
<h3>How to Find the Slope of a Line?</h3>
When given an equation of a line, the slope (m) of the line can easily be determined if the equation is written in the slope-intercept form. The slope-intercept form of the equation of a line is expressed as: y = mx + b.
The "m" in the equation is the slope of the line.
The slope of two lines that are parallel to each other are always the same.
Rewrite the equation, 6x + y = -3
y = -3 - 6x
y = -6x - 3
The slope in 6x + y = -3 is -6. The line that is parallel to the line would also have the same slope.
Therefore, the slope of a line parallel to the line whose equation is 6x + y = -3 is: -6.

So you have to decrease £30 by 20%
To do this, an easy way would be to first take away 100% from 20% because you are DECREASING :
100 - 20 = 80
Then divide your answer by 100 :
80 / 100 = 0.8
This means 0.8 is going to be your multiplier so you do
0.8 * 30 = 24
Answer = £24
