A student ticket for a high school basketball game costs \( \$ 3.00 \). A monthly game pass costs \( \$ 20.00 \). Which inequality represents the number \( x \) of times that a student must attend a basketball game for the monthly pass to be the better deal? \( 3 x<20 \) \( 3 x \leq 20 \) \( 3 x>20 \) \( 3 x \geq 20 \)
