Heather and William are at their local Pokemon specialty store which is running a 20% off sale when you purchase 5 packs of cards. They are both purchasing 5 packs, and each pack costs $4.25 (taxes included)

Answer 1

To calculate the total cost for Heather and William when they each purchase 5 packs of cards at a 20% discount, follow these steps:

1. Determine the total cost of 5 packs without the discount: \[ \text{Cost of one pack} = $4.25 \] \[ \text{Total cost for 5 packs} = 5 \times 4.25 = $21.25 \]

2. Calculate the 20% discount on the total cost: \[ \text{Discount} = 20% \text{ of } 21.25 = 0.20 \times 21.25 = $4.25 \]

3. Subtract the discount from the total cost: \[ \text{Total cost after discount} = 21.25 - 4.25 = $17.00 \]

Thus, each of them will pay $17.00 for their 5 packs of cards after the discount.

Since both Heather and William are making the same purchase, each of them pays $17.00.
