To find the final cost after applying a 20% coupon to the original cost of groceries, follow these steps:
1. Calculate the amount of the discount:
\[
\text{Discount} = \text{Original Cost} \times \text{Discount Rate} = 240 \times 0.20 = 48
\]
2. Subtract the discount from the original cost to find the final cost:
\[
\text{Final Cost} = \text{Original Cost} - \text{Discount} = 240 - 48 = 192
\]
Thus, the final cost after the coupon was used is **$192**.
