so x=5
substituting for x in the equation we get:

Ans C: 16
Q 1. 1,776 and 1,396
q 2. 1,250
q 3. 3.5 million
The answer is 7/16 in decimal it would be 0.4375 hope this helps
For a), wouldn't you multiply the cost of a twin by the quantity of a twin beige (N) and the cost of a queen by the quantity of the queen beige (N) and then the cost of the king by the quantity of the king beige (N) for CN and do the same thing but with the south quantities?
And then for b), it's just comparing which one had the most money and find the difference...
And then C), would be relatively self explanatory where CN would be the potential profit in N and CS would be the potential profit in S and then CN+CS would be the potential profit total?
