To find the final cost after the coupon was applied, we first need to calculate the amount of the coupon discount.
1. Calculate the discount amount:
\[
\text{Discount} = \text{Original Cost} \times \text{Discount Rate} = 210 \times 0.25 = 52.5
\]
2. Subtract the discount from the original cost to find the final cost:
\[
\text{Final Cost} = \text{Original Cost} - \text{Discount} = 210 - 52.5 = 157.5
\]
So, the final cost after the coupon was used is **$157.50**.
