Movement of the Demand Curve. When there is a change in the quantity demanded of a particular commodity, because of a change in price, with other factors remaining constant, there is a movement of the quantity demanded along the same curve.
Explanation:
I think it's $840
For markup, it's 80% which means 4/5
GP/Cost = 4/5
GP/4200 = 4/5
5×GP = 4×4200
5GP = 16800
GP = 16800÷5 = 3360
Therefore, if we less the markup from the cost, what is left is 4200-3360 = 840
I'm a little bit unsure but I tried to help .. please do consult one more answer from an another brainly :)
