Answer:
To complete the required $m dollars for her college, she needs $(m - 60,000).
Step-by-step explanation:
Suppose Rebecca needs $m to complete her college education,
because she has a yearly scholarship of $10,000, she would have $10,000 × 4 = $40,000 for the four years she would spend in college.
Together with her savings of $20,000, she has $20,000 + $40,000 = $60,000 in total.
Therefore to complete the required $m dollars for her college, she needs $(m - 60,000).
