Terry had 3 times as many $2-notes as $5-notes. He had $385 altogether. How many $5-notes did Terry have? Ans: ___

1. Define a variable for the number of $5-notes and express the number of $2-notes in terms of this variable.

Let $x$ be the number of $5-notes.
Then the number of $2-notes is $3x$.

2. Form an equation based on the total value of the notes and solve for $x$.

Value of $5-notes = $5x$
Value of $2-notes = $2(3x) = 6x$
Total value = $5x + 6x = 11x$

Given the total value is $385:
$11x = 385$
$x = \frac{385}{11} = 35$
