The manufacturer of banjos spends $250 to make each banjo and sells them for $400. the manufacturer also has fixed costs each month of $4500.
find the cost function c when x banjos are manufactured.

The cost for making x banjos is c = $ 400 x

Step-by-step explanation:

Given as :

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 1 banjos , the making cost = $ 250

∴  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
