Answer:
C=P-0.4x
Explanation:
Step one:
we want to find the expression for the cost of any type of shirt for an applied discount of 40%.
let the price of any shirt be P
let the cost of any shirt be x
and also the price after discount applied be C
Step two:
The discount is
=40/100*x
=0.4*x
=0.4x
Hence the cost of the shirt will be the initial cost minus the discount
C=P-0.4x
