Original price = $20
Markup percentage = 65
Markup amount = 0
What is the profit?
65% of 20 = $12
Therefore Markup amount = $12
Profit = Original price + markup amount
= $20 + $12
= $32
Well since 19/50 can't be simplified you have to double 9/25 which is 18/50 so then add 18 + 19 = 37 So 18/50 + 19/50 = 37/50 so 37/50 of the students ride the bus or walk to school.
I'm not sure that I am 100% right but I'll give it a shot.
50+75= 125*0.35=43.75
$43.75
M = (1,4)
N = (5,2)
For M, you simply move to 1 on the x axis abs for 4 you move on the y axis. Same does for N, for 5 you move on the x axis and for 2 you move on the y axis.
