Answer: The sales price is $13.78
The original price is $57.41. It is selling at 76% off.
First, we need to find the discount. To find the discount, we need to find out what is 76% of $57.41
-------------------------------------------------
Find discount
-------------------------------------------------
76% x $57.41 ← change the percentage to decimal
= 0.76 x 57.41
= $43. 63 (nearest hundredth)
Now that we know the discount, we can find the sales price by subtracting the discount from the original price.
-------------------------------------------------
Find sales price
-------------------------------------------------
$57.41 - $43.63 = $13.78
-------------------------------------------------
The sales price is $13.78.

So for the triangle you would use the formula A= 1/2 bh (b represents the measurement of the base, h represents the height)
A= 1/2 30(40)
A= 1/2 1200
A=600
Now for the rectangle you use the formula A= l x w (l represents length, w means width)
A= 100 x 40
A= 4000
Now you just add the two answers together
A= 4000 + 600= 4600
Answer:
First, I go by finding <em>x</em><em> </em>and <em>r</em>.
After that, put the numbers (ie. x= # and r=#) into the equations. Check it by finding L.H.S and R.H.S. (ie. left hand side and right hand side)
If you are still confused, comment down and I'll try to provide better explanation!
