Not enough information, because we do not know what b or c is.
The BEST ANSWER is: 4b + 3c is the total amount Marina spent.

You replace the letters into numbers...
Since (st) is the same thing as (s × t), it would be 32 × 45, which equals to 1,440.
Then replace the r with 5, so now it's (6 × 5), instead of (6r).
st ÷ (6r) → 1,440 ÷ 30 = 48
Value of st ÷ (6r) = 48
