(03.02 lc) rylan paid a total of $4,120.00, including principal and interest, over an 18 - month period, to pay off his credit card. choose the equation that could be used to solve how much, on average, he paid in addition to the $172.00 average minimum monthly payment. (172 + x)18 = 4,120 172x + 18 = 4,120 18x + 172 = 4,120 172(18 + x) = 4,120
Answer
# Explanation:
## Step1: Define the variable
Let $x$ be the additional amount paid each month.
## Step2: Calculate the total payment
The average minimum monthly payment is $172$ and the additional amount per month is $x$. So the total monthly payment is $(172 + x)$.
The payment period is 18 - months. The total amount paid is $4120$. So the equation representing the total payment is $(172 + x)\times18=4120$.
# Answer:
$(172 + x)\times18 = 4120$ (first option)
