Answer:
20%
Step-by-step explanation:
Find the difference of both prices.
150 - 120 = 30
Calculate the ratio of the decrease in price to the original price.
30/150 = 0.2
Multiply the decimal by 100 to get your percentage.
0.2(100) = 20
You can do this by taking away the second equation from the first to get rid of the x terms so:
7x - 7x = 0
-5y - -9y = - 5y + 9y = 4y
22-6 = 16
So you are left with the equation:
4y = 16
Divide both sides by 4 to find y
y = 4
