To find the final cost after applying the coupon, we first need to calculate the discount amount and then subtract it from the original cost.
1. **Calculate the discount:**
\[
\text{Discount} = \text{Original Cost} \times \text{Discount Rate}
\]
\[
\text{Discount} = 240 \times 0.20 = 48
\]
2. **Calculate the final cost:**
\[
\text{Final Cost} = \text{Original Cost} - \text{Discount}
\]
\[
\text{Final Cost} = 240 - 48 = 192
\]
Therefore, the final cost after the coupon was used is **$192**.
