Let's define the number of months Nicholas needs to collect more baseball cards as \( m \).
Currently, he has 95 cards and plans to collect an additional 15 cards each month. To find the total number of cards he will have after \( m \) months, we can set up the following equation:
\[ 95 + 15m = 200 \]
Now, let's solve the equation for \( m \):
- Subtract 95 from both sides:
\[ 15m = 200 - 95 \] \[ 15m = 105 \]
- Divide both sides by 15:
\[ m = \frac{105}{15} \] \[ m = 7 \]
Equation: \( 95 + 15m = 200 \)
Time it will take: 7 months
Nicholas will need 7 months to collect enough baseball cards to reach a total of 200 cards.
