OFFER A is cheaper.
Step-by-step explanation:
Given,
OFFER A
Pack of 5
£2.75
Pay for 3 packs get 1 free
And
OFFER A
Pack of 5
£2.75
Pay for 3 packs get 1 free
To find which offer is cheaper.
<u>For OFFER A</u>
For 4 Packets he needs to pay £2.75
He needs to buy 40 batteries.
He needs to buy 40÷(4×5) = 2 packets.
Total cost = £2.75
×2 = £5.5
<u>For OFFER B</u>
For 4 Packets he needs to pay £2.52
He needs to buy 40 batteries.
He needs to buy 10 packets.
After discount he has to pay = £2.52
-(£2.52
×
) = £1.68
Total cost = £1.68×10 = £16.8
Hence,
OFFER A is cheaper.

Answer:
x=1 and y=5
Step-by-step explanation:
simultaneous equations: substitution method
2x+4y=22----equation 1
7x+y=12---equation 2
from equation 2 make y the subject
y=12-7x----equation 3
substitute y into equation 1 to find x
2x+4(12-7x)=22
2x+48-28x=22
collect like terms
2x-28x=22-48
-26x=-26
divide by -26
-26x/-26=-26/-26
x=1
substitute x=1 into equation 3
y=12-7(1)
y=12-7
y=5
therefore, x=1 and y=5
