The total amount repaid by Melvin for the specified case is given by: Option C. $1,440
For finding the total amount repaid, we need to find how repeated addition can be evaluated using multiplication.
How to interpret integral multiplication?
Suppose that there are two positive integer numbers( numbers like 1,2,3,.. ) as a and b
Then, their multiplication can be interpreted as:
[tex]a \times b = a + a + ... + a \: \text{(b times)}\\\\a \times b = b + b +... + b \: \text{(a times)}[/tex]
For example,
[tex]5 \times 2 = 10 = 2 + 2 + 2 + 2 + 2 \: \text{(Added 2 five times)}\\or\\5 \times 2 = 10 = 5 + 5 \: \text{(Added 5 two times)}[/tex]
Since Melvin paid $60 for 24 months, so the amount he paid is $60 added 24 times, or:
Total amount paid by Melvin for furniture buying = 60 + 60 + ... + 60 (24 times) = [tex]24 \times 60 = 1440 \text{\: (in dollars)}[/tex]
Thus, the total amount repaid by Melvin for the specified case is given by: Option C. $1,440
