Jayden used a Groupon at the local pizza shop. Instead of paying $15, for the pizza, he paid $12. Haley and Arianna agree that the percent of decrease is 20% but their explanations differ. Haley says to find the 20%, you have to determine what percent of 15 is 12. Arianna thinks you have to determine what percent of 15 is 3. Who is correct?

Ariana is correct. The difference in the price is $3. So the percentage that you saved has to equal $3.

Step-by-step explanation:

$15.00 x .10 or 10% = $1.50

$1.50 x 2 will give you 20%

$1.50 x 2 = $3.00

$15.00-$3.00 = $12.00

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
