Well. im not 100% sure if this is correct. but what i did was did 5 x 8. which equals 40. so then i did 5 x 3. which equals 15. then i did 5 x 4. which equals 20. hopefully im correct. hope this helped! :)
We are given with the formula p = 200k - 500 a) The constraint for this formula is obtained from the idea that the profit must be positive 200k - 500 > 0 k > 500/200 k > 2.5 b) To make 14000 profit 14000 = 200k - 500 k = 72.5 or 73 knives must be sold
