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.
