Question 1121765: Please help me to solve this
A shopkeeper bought x pens for $21.
a) write down an expression, in terms of x, for the cost, in cents, of each pen
b) the shopkeeper gave 2 pens to his sons and sold each of the remaining pens at 8 cents more than he paid for it. Write down an expression, in terms of x, for the selling price of each pen.

You can put this solution on YOUR website!
the cost for each pen will be 2100 / x

the selling price for each pen will be (2100 / x) + 8

that should be your solution.
