Aprice increases from $82 to $89.38. what is the percent of change

the cost goes up $7.38 which is 9% of $82

We first must find the difference between the two prices. So let's subtract:

Now we take this difference and divide it by the original amount that the price was:

This is the decimal form of the answer. In order to make it a percent, we must multiply it by 100:

So the percent change in this price is 9%.

i think the answer is b x = 1, y = 35/2
