Question

c. Based on the book price per copy you calculated in the previous task, write a function to represent your income if you sell x copies.

Answer 1

OK, post the formula for price and cost of production up here first.

Answer 2

Y = 1,550 + (4x)
4 x 50 = 200
1550 + 200 is 1750
so that

Answer 3

i put that as my answer

Answer 4

No, sorry! You need to work out profit.

Answer 5

oh so how?

Answer 6

No sorry!
50x - (1,550 + (4x))

Answer 7

No 'Y='.

Answer 8

so just no Y

Answer 9

You want profit, so put how much it costs to manufacture X copies (1,550 + (4x))
And then subtract that from how much you get from selling X copies, 50x.

Answer 10

so i put (1550+(4x))+50x?

Answer 11

Nah, 50x - (1,550 + (4x)). Other way round, and you subtract.

Answer 12

ok thanks
