C. \$[/tex]151.77
D. \$368.59



Answer :

To determine how much of the \[tex]$4400 charge Carlton made during the first month has been paid off, we need to sum the principal paid amounts from months 2 through 7. Here is a step-by-step breakdown: 1. Month 2: - Principal paid: \$[/tex]25.67

2. Month 3:
- Principal paid: \[tex]$25.52 3. Month 4: - Principal paid: \$[/tex]25.37

4. Month 5:
- Principal paid: \[tex]$25.22 5. Month 6: - Principal paid: \$[/tex]25.07

6. Month 7:
- Principal paid: \[tex]$24.93 Next, we sum these amounts to find the total principal paid by Carlton from month 2 to month 7. \[ \text{Total Principal Paid} = 25.67 + 25.52 + 25.37 + 25.22 + 25.07 + 24.93 = 151.78 \] Thus, Carlton has paid off \$[/tex]151.78 of the \[tex]$4400 charge made during the first month. The correct option is: C. \$[/tex]151.78
