Answer:
both are answered below
Step-by-step explanation:
- let us assume that , he buys y number of roses and x carnations.
- the total cost cant be more than $30.
- the cost of each rose : $3
- the cost of each carnation : $2
- so, the cost of all roses that he buys : 3x
- the cost of all carnations that he buys : 2y
- the required inequality will be : 3x+2y
30
- the graph is in the attachment.
- by seeing graph, possible x,y values: (2,12) , (6,6) , (8,3)
[where x represents no. of carnations that he buys , y represents no. of roses that he buys ]

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.
F you just want to see the really short way, just skip down to AAAAAAAAAAAA
so, here is the long explanation
exponential properties
don't forget pemdas
2x^2=2(x^2)
so
=
AAAAAAAAAAAAAAAAAAAAAAAA
so we see
the original equatio is
remember
so we can seperate the constants
we know that the placeholders cannot affet the position of the constants unless they are grouped together which they are not
terfor the answer must have 2/3 in it
the only one that hsa that is A
