Jane is saving up to purchase her first bicycle. The new bike costs $185. Jane got $50 for her birthday and plans to put that towards the bicycle. To save the rest of the money, Jane plans to put asides an additional $15 per week until she has saved enough to purchase the bicycle. Write an equation that represents Jane’s savings towards earning her bicycle. Use w to represent the number of weeks.

Question

A) 15w = 185
B) 15w + 50 = 185
C) 50 w + 15 = 185
D) 15w - 50 = 185

Answer 1

To model Jane's savings towards purchasing the bicycle, we note the following details:

1. The bike costs $185.
2. Jane has already saved $50 from her birthday.
3. She plans to save an additional $15 per week.

Let $w$ represent the number of weeks Jane saves.

Her total savings can be represented as the initial $50 plus $15 for each week she saves, which is expressed as $15w$.

So, the equation representing Jane's savings would be:

$$15w+50=185$$

Therefore, the correct answer is:

B) 15w + 50 = 185
