SAT Question d72a2b4d: Percentages answer and explanation with Desmos solution

Choice C is correct. It's given that the price of the collectible card was $$15.50$ in March and $$17.36$ in April. It's also given that the price of the collectible card in April was $p\%$ of the price in March. It follows that $$17.36$ is $p\%$ of $$15.50$. Therefore, the value of $p$ can be calculated by solving the equation $17.36=\left(\frac{p}{100}\right)\left(15.50\right)$, or $17.36=\frac{15.50p}{100}$. Multiplying each side of this equation by $100$ yields $1,736=15.50p$. Dividing each side of this equation by $15.50$ yields $112=p$. Therefore, the value of $p$ is $112$.
