To represent Jane's savings towards earning her bicycle, we need to account for two things:
- The $50 she already has from her birthday.
- The $15 she plans to save each week, represented by \( w \) (the number of weeks).
The total amount she needs to save is $185. Therefore, we can write the equation that represents her total savings (the $50 plus the amount saved weekly) equal to the total cost of the bicycle:
\[ 15w + 50 = 185 \]
So, the correct answer is:
B) 15w + 50 = 185
