4,200 with a 35% markdown
Bumek [7]

Answer:

4200 with 35% markdown: 2730

5000 with 44% markdown: 2800

Step-by-step explanation:

To calculate the price of an item including the markdown, multiply the original price by (1 minus markdown).

Convert the markdown percentage to decimal form before subtracting.

4200 with a 35% markdown: (35% = 0.35)

4200*(1 - 0.35)

= 4200 *(0.65)

= 2730

5000 with a 44% markdown: (44% = 0.44)

5000*(1 - 0.44)

= 5000*(0.56)

= 2800

Therefore, the sale price for $4200 with a 35% markdown is $2730, and the sale price for $5000 with a 44% markdown is $2800.

Find the midpoint of the line segment with endpoints (-4, 5) and (-6, 7)
Verizon [17]

Answer:

Midpoint is (-5,6).

Step-by-step explanation:

Given points are (-4,5) and (-6,7)

Midpoint of points (x_1,y_1) and (x_2,y_2) is \left (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}  \right )

Therefore, \left (\frac{-4+(-6)}{2},\frac{5+7}{2}  \right )=\left (\frac{-4-6}{2},\frac{5+7}{2}  \right )

                                         =\left (\frac{-10}{2},\frac{12}{2}  \right )

                                         =(-5,6)
