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

Question

What was the final cost after the coupon was used? 

Answer 1

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.
