Michele has $50. She plans to save $15 per week until she has a total of $230.

Which equation matches this scenario?

y is equal to 50 x plus 15

1 answer

To match Michele's savings scenario, we can set up an equation where:

  • \( y \) is the total amount saved.
  • \( x \) is the number of weeks she saves.

Michele starts with $50 and adds $15 each week. After \( x \) weeks, her total savings can be represented as:

\[ y = 50 + 15x \]

This matches the structure:

  • Initial amount (starting total) is 50.
  • Each week she adds 15 times the number of weeks (\( x \)).

Looking through the provided options:

  1. \( y = -15x + 50 \): This shows a decrease in total which doesn't apply here.
  2. \( y - 110 = 15(x - 4) \): This is more complicated but essentially conveys savings but we would need to analyze it closely; we're not going with this.
  3. \( y = 50x + 15 \): The coefficients don't align with the saving per week properly.

None of the equations perfectly represent Michele's savings scenario. The closest equation should be:

\[ y = 50 + 15x \]

However, in the proposed answers, the second option can be rearranged to reflect a similar structure after certain operations, but it's not straightforward without additional context or manipulation.

Hence, based on the options provided and the typical way of forming the equation, if we had to choose one, we would clarify that it doesn't directly match Michele's scenario without reformatting.

If you seek an exact selection among those options, it appears that option two might relate better after appropriate manipulation, but as expressed, the clear equation would be \( y = 50 + 15x \).
