lin_form_endings_v1_1248542787_17
Let $a$ and $b$ be positive integers such that $1 \leq a \leq 31$ and $1 \leq b \leq 42$. Let $t$ be an integer satisfying $50 \leq t \leq 1880$ and $t = 20a + 30b$. Determine the number of possible values of $t$. Multiply this number by 6607, and compute the remainder when the result is divided by 96267.
