Let's denote the number of months Nicholas collects cards as \( m \).
Nicholas currently has 95 baseball cards and plans to collect 15 more cards each month. Therefore, the number of baseball cards he will have after \( m \) months can be expressed as:
\[ 95 + 15m \]
Nicholas wants to have a total of 200 cards, so we can set up the equation:
\[ 95 + 15m = 200 \]
Now, we can solve for \( m \):
- Subtract 95 from both sides:
\[ 15m = 200 - 95 \]
\[ 15m = 105 \]
- Divide both sides by 15:
\[ m = \frac{105}{15} \]
\[ m = 7 \]
It will take Nicholas 7 months to collect enough cards to reach a total of 200 baseball cards.
