Ответ:
Aiden can have a maximum of 166 copies.
Step-by-step explanation:
Aiden has $15.00 on his copy card.
Each time he uses the card to make a photocopy $0.06 is deducted from his card.
Means cost of 1 copy is $0.06
Let the total number of copies be = x
So, total copies will be =
He wants that there be at least $5.00 left on his card when he is finished.
So, the maximum number of copies he can have is given by
Solving this we get;
rounded to 166 pages.
Therefore, Aiden can have a maximum of 166 copies.
