   Inequality expressions

   These are expressions not separated by an equality sign.

   Since 1 dozen is equivalent to 12, hence  D dozen donuts for $4.50 each is given as $12(4.50)

   The price of  B boxes of cookies for $2.25 each will be 2.25B

   If she can only spend at most $30, then the inequality could be used to determine how many of each item Sally can purchase will be 12(4.50) + 2.25B ≤ 30

   The less than or equal to sign is used since the maximum amount she can spend is $30
