Final answer:
David would pay less for the laptop on the store's website compared to the store after the discounts.
Step-by-step explanation:
To compare the prices of the laptop at the store and on the store's website, we need to calculate the final price after all the discounts.
(a) On the store's website, the laptop is being sold at a 60% discount, so David would pay 40% of the regular price: 0.40 * $719 = $287.60.
(b) At the store, the laptop is being sold at a 50% discount. After applying the in-store-only coupon for an additional 10% off, David would pay 90% of 50% of the regular price: 0.90 * 0.50 * $719 = $323.55.
(c) Based on the calculations, David would pay less for the laptop on the store's website compared to the store. Therefore, the correct statement is: David would pay less for the laptop on the website.
