I think there’s a mistake on page 11, Question 6(c) , Cos(66)*46.2= 18.791… roughly 18.8 and not 17.3 as it is given in the answer. Please resolve this issue if possible.

I think the answer to question 8 b) is wrong because it asks for 4 lines to be drawn but you have only drawn 3.
If i am wrong, can you please correct me.
Thankyou.

Your answer to the question 6 part c is wrong it should be 18.79. Your method is correct though.

it’s modified now

Are you sure your inequalities graph is correct? It should be having 4 lines. Please revise.

Thankyou.

one of the lines is not shown… x+2y>400

For question 8 b isn’t there supposed to a fourth line passing through (0,200) and (400,0)?

yes it should be

Very helpful. Thanks a lot !
