Suha should buy the 50 envelopes from Letter2send.
Step-by-step explanation:
Step 1:
At Letters2send, a pack of 25 envelopes costs £3.49. We need to determine how many packs will have 150 envelopes.
The number of packs = [tex]\frac{150}{25} = 6.[/tex]
So 6 packs of 25 envelopes will have 150 packs.
The cost for 150 envelopes = [tex]3.49 (6) = 20.94.[/tex]
So at Letters2send, 150 envelopes cost £20.94.
Step 2:
At the stationery word, if you buy 2 packs of 10 envelopes, you get a pack of 10 envelopes for free. So 3 packs cost £4.20. You get 30 envelopes for £4.20.
The number of 30 envelope packs = [tex]\frac{150}{30} =5.[/tex]
The cost for 150 envelopes = [tex]4.20 (5) = $21.[/tex]
So in the stationery world, 150 envelopes cost £21.
Step 3:
150 envelopes from Letters2send are cheaper than the stationery world so Suha should buy the envelopes from Letters2send.
