Answer:
So Price after discount would be 17.5 on February 1st
Step-by-step explanation:
Given:
Original Cost =57.75
Off Price = 70%
To Find:
Price after discount = ?
Solution:
We have to find the price after discount which is given by the formula
Price after Discount = Original Cost - Discount Price
We have to find the value of discount price
Discount Price = off Price * Original Cost
Putting in the values
Discount Price = 70 % * 57.75
it becomes
Discount Price
It becomes
= 40.25
Now
Price after Discount = Original Cost - Discount Price
Putting in the values
it becomes
Price after Discount = 57.75-40.25
= 17.5
So Price after discount would be 17.5 on February 1st
He is correct
basically you have
h times base1+h times bsae 2 all divided by 2
that equals
(hb1+hb2)/2
if we undistribute h using distributive property which is ab+ac=a(b+c)
(h)(b1+b2)/2
if you split the trapezoid in half with a horizontal line that passes through the halfway point of the height and take those two shapes and put them side by side and cut the triangles off the ends and add them, you will see why this is true
the reason is becuase you can get to the area formula from that is height times (b1+b2)/2
