Question

Sally wants to purchase D dozen donuts for $4.50 each and B boxes of cookies for$2.25 each. She can spend at most $30. Which inequality could be used to determine how many of each item Sally can purchase? Answers 1. dangkhoa 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

### 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
