Explanation

To determine Kate's possible gross incomes:
\(\frac{1}{4}\) of her gross income is 13,470
\(\frac{1}{4} (x) = 13470\) → \((4)\frac{1}{4}(x) = (4)13470\)→ \(x = 53,880\)

1/3 of her gross income is 13,470
\(\frac{1}{3} (x) = 13470\) → \((3)\frac{1}{3} (x) = (3)13470\) → \(x = 40,410\)

Kate's gross income falls between $40,410 and $53,880, so the last four answer choices B,C,D, E are correct.
