Question

Tracy has to buy comic books to pay for a movie ticket. Each comic book costs 10$. Write an inequality that can be used to determine how many comic books, b, tracy can buy.

Answer 1

Answer:

$35 - 3b is greater or equal to $10

Step-by-step explanation:

Remember that:

     Dollars spent on an item = (cost of one item)*(number of items), so –

        Dollars spent on comic books = $3b

“Tracy has $35 to buy comic books and to pay for a movie ticket”   means

     (Money spent on comic books) + (money spent on movie ticket) ≤ $35

     (Money spent on comic books + $10 ≤ $35

                  $3b + $10 ≤ $35                           [just substituting values]

Now, we must modify the inequality, so remember the rules –

       $35 ≥ $3b + $10      [reverse right-to-left reverses the sense of the inequality;

             $35 is greater or equal to the total amount Tracy can spend]

       $35 - $3b  ≥ $10   [subtract positive 3b from both sides

                   keeps the sense of the inequality]
