Suha is going to buy 150 envelopes.
Katyanochek1 [597]

Suha should buy 150 envelopes from shop 1 because the cost in shop 1 is 0.06 less shop 2.

<u>Step-by-step explanation</u>:

Total number of envelopes = 150

<u>The cost of envelopes :</u>

  • Pack of 25 envelopes in shop 1 = 3.49
  • Pack of 10 envelopes in shop 2 = 2.10
  • Buy 2 packs get 1 pack free in shop 2.

<u>Shop 1 :</u>

The number of packs to buy 150 envelopes = 150 /25 = 6 packs

The total cost to buy 6 packs = 6 × 3.49 = 20.94

The cost of 150 envelopes in shop 1 is 20.94

<u>Shop 2 :</u>

The number of packs to buy 150 envelopes = 150 /10 = 15 packs

  • For each 2 packs you get 1 pack free.
  • 10 packs + 5 free packs = 15 packs

The total cost to buy 10 packs = 10 × 2.10 = 21

The cost of 150 envelopes in shop 2 is 21

The difference between shop 2 and shop 1 = 21 - 20.94 = 0.06

Therefore, the cost in shop 1 is 0.06 less than shop 2. So, Suha should buy 150 envelopes from shop 1.
