Answer:
55
Step-by-step explanation:
Original price = 50 and percent markup is 10%
The increase is the original price times the percent markup
increase = 50 * 10%
increase = 50*.10
= 5
The new price is the original price plus the increase
new price = 50 + 5
= 55

Using the midpoint formula, the coordinates of endpoint H are (4, -6).
<h3>The Midpoint Formula</h3>
The midpoint formula is given as: 
<em>Where</em>,
= coordinates of the midpoint
= coordinates of the first point
= coordinates of the second point
Given the following:
= M( 6,-4)
= G(8,-2)
= H(?, ?)
Plug in the values into the midpoint formula

Solve for the x-coordinate and y-coordinate separately



Therefore, using the midpoint formula, the coordinates of endpoint H are (4, -6).
