SAT Question 191d167b: Percentages answer and explanation with Desmos solution

Choice B is correct. It's given that the number of students enrolled in an interior design program this year is $147\%$ of last year's number, which is $200$. $147\%$ of $200$ can be expressed as $\left(\frac{147}{100}\right)\left(200\right)$, or $\left(1.47\right)\left(200\right)$, which is equivalent to $294$. Therefore, $294$ students are enrolled in the interior design program this year.
