Answer 1

Let the cost of one battery be x

the cost of a pack of 8 batteries = 3.99

Now,

8x =3.99

x = 3.99/8

x = 0.49(approximately)

Second Condition,

cost of a pack of 6 batteries = £2.79

Now,

6x = 2.79

x= 2.79/6

x=0.46(approximately)

Therefore, the 8 pack batteries has greater price than 6 pack of batteries.
