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 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.
