the cost of groceries for the nguyen family was $210.00. the family used a coupon for 25% off the cost. what was the final cost after the coupon was used?

Answer 1

To find the final cost after applying the 25% off coupon, you can follow these steps:

1. Calculate the discount amount:
   \[ \text{Discount} = \text{Original Cost} \times \left(\frac{\text{Discount Percentage}}{100}\right) \] \[ \text{Discount} = 210.00 \times 0.25 = 52.50 \]

2. Subtract the discount from the original cost to get the final cost:
   \[ \text{Final Cost} = \text{Original Cost} - \text{Discount} \] \[ \text{Final Cost} = 210.00 - 52.50 = 157.50 \]

Therefore, the final cost after the coupon was used is $157.50.
