Decide whether the following statement makes sense (or is clearly true) or does not make sense (or is clearly false) Explain your reasoning The price of tuition has quintupled since my parents went to school that's a $400 \%$ increase in price Choose the correct answer below. A. The statement makes sense. The percent increase is always divided by 80 to find the factor by which the original price has changed. B. The statement does not make sense. If the tuition quintuples, then the price increases by $500 \%$. C. The statement makes sense A $400 \%$ increase in price corresponds to a price that is $500 \%$ of the original price D. The statement does not make sense. If the tuition quintuples, then the price increases by $300 \%$.

Find the percent change if a quantity changes from $P_{1}$ to $P_{2}$. \[ P_{1}=1.9, P_{2}=0.79 \] The percent change is $\%$. (Round to the nearest tenth as needed.)
