Old price: p1 = $ 3.90;
New price: p2 = $ 3.40.
The percentual decrease is given by
d(%) = [ (p2 - p1) / p1 ] * 100 %
d(%) = [ (3.40 - 3.90) / 3.90 ] * 100 %
d(%) = [ - 0.50 / 3.90 ] * 100 %
d(%) = - 0.128 * 100 %
d(%) = - 12.8 % (approximately)
So the price fell 12.8 % approximately.
I hope this helps. =)

Step-by-step explanation:
Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
Answer:
Domain - (0,1,2,3,4) Range - (32,27,22,17,12)
Domain - (0,1,2,3,4) Range - (36,32,28,24,20)
Step-by-step explanation:
The # of knots is actually the X values which is also the definition of the word, "Domain" whilst the Length of the ropes is the y values, aka the range.
