Question

The cost of groceries for the Goodin family was $240. The family used a coupon for 20% off the cost.
What was the final cost after the coupon was used?

Answer 1

To find the final cost after applying the coupon, we need to calculate the discount amount and then subtract it from the original cost.

1. Calculate the discount amount:
\[
\text{Discount} = \text{Original Cost} \times \text{Discount Percentage}
\]
\[
\text{Discount} = 240 \times 0.20 = 48
\]

2. Subtract the discount from the original cost to find the final cost:
\[
\text{Final Cost} = \text{Original Cost} - \text{Discount}
\]
\[
\text{Final Cost} = 240 - 48 = 192
\]

The final cost after the coupon was used is **$192**.
