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

1 answer

To find the final cost after applying the 20% coupon to the original grocery cost of $240, follow these steps:

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

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

Thus, the final cost after using the coupon is $192.
