Let the notebook cost x, then Mark spent:
25x + 25*1.25 = 156.25
25x + 31.25 = 156.25
25x = 156.25 - 31.25
25x = 125
x= 125/25
x= 5
It is A triangle with a base length of 2in. and a height of 16in.
You would use an equation similar to 44x = 66 or x = 66/44.
The total length of the row is 66 meters; you want 44 equal sections of x length.
