Step-by-step explanation:
Let
x ------> the number of dogs Larry walked
y -----> the number of dogs Kyle walked
we know that
The linear equation that represent this scenario is equal to

The first step to determine the percentage of increase is to
compute for the difference of consumer price index in value.
231.11 (consumer price index for 2012) – 211.4 (consumer
price index for 2007) = 19.71 (increase)
To compute for the percentage of increase, you need to
compare the increase to the consumer price index for 2007.
19.71/211.4 = 9.3% increase
Since the two numbers vary directly, if Y is quadrupled, X will do the same. 2 times 4 is 8, 15 times 4 is 60.
X = 60.
Hope that helps!! :)
