Jessica's yearly cost to rent her apartment is $6.300. Which equation represents the total cost of rent per year, c, based on the amount she pays each month, m? A. 525c =m
B. 525m = c
C. 525 + m=c
D. m : 525 = c

I’m gonna go with B, 525m=c

Explanation:
m represents months
c represents total cost

C has to be on its own side of the equation for one. m is the number of months and you multiply this by the cost per month to find the total cost.
