Charlie has \( x \) state quarters. Ty has 3 more quarters than Charlie, so Ty has \( x + 3 \) quarters. Vinnie has 2 times as many quarters as Ty, so Vinnie has \( 2(x + 3) \) quarters.
Write and simplify an expression to show how many state quarters they have in all.
Expression:
\[ x + (x + 3) + 2(x + 3) \]
Simplified expression:
\[ x + x + 3 + 2x + 6 = 4x + 9 \]
In total, they have \( 4x + 9 \) state quarters.
