Answers:
Expression for the total number of quarters is 40*1.20
Amount of money you have left is 6 dollars
===================================================
Explanation:
You start with 40 quarters. 20% of this is 0.20*40 = 8 which means you found 8 more quarters. The total goes from 40 to 40+8 = 48.
A slight shortcut is to write 40*1.20 = 48
--------------
48 quarters = 48*0.25 = 12 dollars
Or you can divide by 4 to determine the total value of the quarters in dollars.
If you spent half (50%) of that money, then you'll be left with 6 dollars.

Answer:
<em>20 sq yd</em>
Step-by-step explanation:
To find the total amount of sq yd's of paint needed, you have to find the area.
The area of a triangle is: A = 1/2 bh
We know:
b = base = 8
h = height = 5
Plug in and solve:
A = 1/2 (8) (5)
A = 1/2 (40)
A = 20
