Final answer:
Mr. Jones contributed $56,480 (Option C). To find out how much Mr. Jones contributed to the savings, subtract the amount saved by Ms. Martin from the total amount saved.
Step-by-step explanation:
To find out how much Mr. Jones contributed, we need to subtract the amount Ms. Martin saved from the total amount saved.
Mr. Jones' contribution can be calculated as:
Total amount saved - Amount saved by Ms. Martin = Amount contributed by Mr. Jones
Given that the total amount saved is $56,480 and Ms. Martin saved $0, we can calculate:
$56,480 - $0 = $56,480
Therefore, Mr. Jones contributed $56,480.
Hence, the correct answer is $56,480 (Option C).
