You can easily make an equation here..
9060=2550+155*n......
155n=9060-2550=6510
5*31n=31*210....
n=210/5=42
C

We can form an equation based on the given information.

Total = 9060
Down Payment = 2550
Monthly Installment = 155

Question : Number of monthly payments.


2550 + n(155) = 9060

155 n = 6510

n = 42.

Thus the best answer is C. Julia made 42 monthly payments.

\(9060 = 2550 + 155n\)

Or, \(155n = 6510\)

Or, \(n = 42\), Answer must be (C) 42

We can let n = the number of monthly payments and create the equation:

2550 + 155n = 9060

155n = 6510

n = 6510/155 = 42

Answer: C
