Let's assume the number of hours Carlos works as a busboy is represented by the variable \( b \) and the number of hours he works as a theater usher is represented by the variable \( u \).
Carlos earns \( 12b \) dollars as a busboy and \( 10u \) dollars as a theater usher.
According to the problem, Carlos's goal is to earn at least \( \$120 \).
So, we can write the inequality as:
\[ 12b + 10u \geq 120 \]
This inequality states that the total earnings from working as a busboy and as a theater usher should be greater than or equal to \( \$120 \).
Carlos works as a busboy making per hour and as a theater usher making per hour. Let be the number of hours he works as a busboy this month, and let be the number of hours he works as an usher. His goal this month is to earn at least total. Using the values and variables given, write an inequality describing this.
