To determine how much money Sierra has to save, let's first calculate the sale price of the bike.

1. **Calculate the discount:**
The original price of the bike is $200, and it is on sale for 40% off.
Discount = 40% of $200 = 0.40 * $200 = $80.

2. **Calculate the sale price:**
Sale price = Original price - Discount = $200 - $80 = $120.

3. **Calculate how much her parents will pay:**
Her parents agree to pay $75.

4. **Calculate how much Sierra needs to pay:**
Amount Sierra needs to pay = Sale price - Amount parents will pay = $120 - $75 = $45.

Therefore, the amount of money Sierra will have to save is **$45**, which corresponds to option **A**.
