Eve is going to buy 30 pens from either shop A or shop B. Shop A: pack of 10 pens for £1.90 Shop B: pack of 5 for £1.10 buy 1 pack and get 1 half price. What is the difference in cost for all 30 pens between the two shops?

£ 0.75

Step-by-step explanation:

Number of pens to be bought = 30

Shop A :

pack of 10 =  £1.90

since Eve is buying 30 pens , this means Eve will buy 3 packs of ten , that is

3 x ( £1.90 ) =  £5.70

Shop B:

pack of 5 =  £1.10

condition :  buy 1 pack and get 1 half price.

since Eve is buying 30 pens , then Eve will buy 3 pack of 5 and get 3 half price , that is :

3(1.10) + 3(0.55)

=  £3.30 + £1.65

= £4.95

Therefore , the difference in cost for all 30 pens between the two shops will be :

£5.70 - £4.95 = £ 0.75

yo answer should be 6 if im not mistaken
