Answer:
We conclude that Linda is right, and that it really is bad because it's a 25% increase.
Step-by-step explanation:
Harry notes that the state sales tax went from 2% to 2.5%.
Therefore, we get the following proportion.
We calculate:
2% : 100% = 2.5% : x
2x=100 · 2.5
2x=250
x=125%
So, we conclude it's a 125% - 100% = 25% increase.
We conclude that Linda is right, and that it really is bad because it's a 25% increase.
