T-shirts are buy one get one free and jumpers are 3 for 2. The normal price of a T-shirt is £5.20 and the normal price of a jumper is £12.20.
How much does it cost to get 5 jumpers and 6 T-shirts using this offer as appropriate?

£64.4

Step-by-step explanation:

"T-shirts are buy 1 get 1 free"

Therefore if you buy 3 T-shirts, you would get the other 3 free So really you are only paying for 3 T-shirts if you want to get 6.

£5.20(3) =  £15.6

"Jumpers are buy 3 for 2"

So you buy three for the price of 2.

3/2 = 5/x,

x = 3.33

We round this up to 4 and solve for the total cost of the jumpers.

12.2(4) = £48.8

Total:

15.6 + 48.8 =  £64.4

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
