A movie ticket cost me $5.60 after a 20% coupon. What was the original price of the ticket?

7.00

Step-by-step explanation:

discount = original price *20%

final price = original price - discount

Substituting the equation for discount

final price = original price - original price*20%

Factoring out the original price

final price = original price (1-20%)

Changing to decimal form and putting the final price

5.60 = original price (1-.2)

5.60 = original price (.8)

Divide by each side by .8

5.6/.8 = original price (.8)/.8

7 = original price

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
