His college Jason can take a maximum of 21 hours each semester between elective classes and core classes each elective class cost $225 per semester hour and each core class costs $275 per semester hour. If he cannot spend more than $6,000 each semester on classes which system of any qualities below can be used is a Herman the number of elective classes e and the number of core classes c he can take each semester?

Answer 1

• D. e + c ≤ 21, 225e + 275c ≤ 6000

Explanation:

Maximum of 21 hours each semester between elective classes and core classes, the required inequality is:

• e + c ≤ 21

Each elective class cost $225 per semester hour and each core class costs $275, the sum is 225e + 275c.

He cannot spend more than $6,000, the required inequality is:

• 225e + 275c ≤ 6000

Correct option is D
