The making cost of each banjos = $ 250
The selling cost of each banjo = $ 400
Let The cost for making x banjos = c
Now,

∴ For making x banjos , the making cost = $ 250 × x
Again,
∵ The selling price of 1 banjos = $ 400
∴ The selling price of x banjos = = $ 400 × x
Hence The cost for making x banjos is c = $ 400 x . Answer
