Final answer:
After calculating the total cost at Value World (£33.83) and Letters2go (£31.90) for 250 envelopes, Betsie should buy the envelopes from Letters2go as it offers the lower price.
Step-by-step explanation:
To determine which shop will give Betsie the best price for 250 envelopes, we need to calculate the total cost at both stores.
- At Value World, a pack of 10 envelopes costs £1.99. To buy 250 envelopes, Betsie needs 25 packs (250 envelopes / 10 envelopes per pack). However, with the deal of buy 2 packs get 1 free, Betsie only needs to purchase 17 packs to get 8 for free (17 paid packs + 8 free packs = 25 packs). The cost at Value World would be 17 packs × £1.99 per pack = £33.83.
- At Letters2go, a pack of 25 envelopes costs £3.19. Betsie would need 10 packs (250 envelopes / 25 envelopes per pack). The cost at Letters2go would be 10 packs × £3.19 per pack = £31.90.
So, Letters2go has the lower price for 250 envelopes at £31.90, compared to Value World's £33.83. Therefore, Betsie should buy the envelopes from Letters2go.
