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. =)
Answer:
c
Step-by-step explanation:
Well the answer couldn’t be C because the arrow has to go to the right not left because for the > in the equation

Answer:
x=20
Step-by-step explanation:
The line is a straight line, which is 180 degrees
x+100+3x = 180
Combine like terms
100+4x = 180
Subtract 100 from each side
100+4x-100=180-100
4x=80
Divide by 4
4x/4 = 80/4
x=20
Answer:

Step-by-step explanation:
We have been given that about 75,000 people visit Paris, France. We are asked to write two equivalent expressions that could be used to find the number of people that visits over a 5- day period
.
To find the number of people over a 5-day period, we will multiply 75,000 people by 5 as:

Commutative property of multiplication states that we can multiply numbers in any order.
Upon switching the order while multiplying, we will get:

Therefore, our required equivalent expressions would be
and
