Answer:
1047 m = c
Step-by-step explanation:
Given : Mr.kelly pays $12,564 a year for rent. His rent is a constant amount each month.
To Find:Which equation represents the amount he pays her month if m=months and c=total rent paid for the year?
Solution :
Since he pays for a year (12 months) = $12,564
Since His rent is a constant amount each month.
He pays for one month = 
Thus the amount he pays per month $1047
If he pays for m months then the total amount(c) of rent for m months
⇒1047 m = c
Hence equation represents the amount he pays her month if m=months and c=total rent paid for the year: 1047 m = c
Answer:
from the working in the photo
SI = PRT /100
1. SI = 400*5*1/100
= 2000/100
= $ 20
2. SI = 1000*8.5*3/100
= 25.5*1000/100
= $ 255
3. SI = 200*9*1/2*100
= 900/100
= $9
4. SI = 20000*12*3/100
= 200*12*3
= 7200
5. SI = 1200*4.5*6/12*100
= 4.5*6
= $27
Amount to pay = Principal + SI
= 1200+27
= $1227 ( But this answer isn't there in the options )
Your expected value is 36*2/6 + -36*4/6, which is equal to $-12.
