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

Step-by-step explanation:

Total number of envelopes = 150

The cost of envelopes :

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.

Shop 1 :

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

Shop 2 :

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.

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 = $\frac{150}{25} = 6.$

So 6 packs of 25 envelopes will have 150 packs.

The cost for 150 envelopes = $3.49 (6) = 20.94.$

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 = $\frac{150}{30} =5.$

The cost for 150 envelopes = $4.20 (5) = $21.$

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.

Austin needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for

klasskru [66]

The cost of labour per hour is $90.56

The total amount paid by Austin is the sum of the total cost of labour and the cost of the parts

Total amount paid = total cost of labour + cost of parts

$553.50 = total cost of labour + $126

total cost of labour = $533.50 - $126

= $407.50

The total cost of labour = cost of labour per hour x total time worked

$407.50 = xx × 4.5

xx = $407.50 / 4.5

xx = $90.56

jasenka [17]

Answer:

See below

Step-by-step explanation:

Essentially, we have to replace "quantifier words" like "All", "Every" by the universal quantifier ∀.

a) ∀ dinosaur x, x is extinct.

b) ∀ real number x, x is positive, negative, or zero.

c) ∀ irrational number x, x is not an integer.

d) ∀ logician x, x is not lazy.

e) ∀ integer x, x²≠ 2,147,581,953.

f) ∀ real number x, x²≠ -1.

In a) and b) we replace the words without major changes. In the other statements, we modify the statement using negation. For example, "No irrational numbers are integers." is equivalent to "Every irrational number is not integer".
