Question

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
a. 52.50
b 157.50
c 185.00
d 262.50

Answer 1

To find the final cost after applying a 25% coupon to the original cost of groceries, we can follow these steps:

1. Calculate the amount of the discount:

   • Since the coupon gives 25% off the cost, we first need to calculate 25% of the original cost, which is $210.00.
   • To do this, multiply the original cost by 0.25 (which is the decimal form of 25%).

   \[ \text{Discount} = 210.00 \times 0.25 = 52.50 \]

2. Calculate the final cost after the discount is applied:

   • We subtract the discount from the original cost:

   \[ \text{Final Cost} = \text{Original Cost} - \text{Discount} \] \[ \text{Final Cost} = 210.00 - 52.50 = 157.50 \]

So, the final cost after the coupon is used is $157.50.

The correct answer is b. 157.50.

Answer 3

Sure! Here's a shorter version:

1. Calculate the discount: \[ \text{Discount} = 210.00 \times 0.25 = 52.50 \]

2. Calculate the final cost: \[ \text{Final Cost} = 210.00 - 52.50 = 157.50 \]

Final cost after the coupon: $157.50 (b).
