What is the total amount that Jerome has paid in interest over the 7 months?

A. \[tex]$65.18
B. \$[/tex]32.18
C. \[tex]$260.72
D. \$[/tex]195.54



Answer :

To find the total amount that Jerome has paid in interest over the 7 months, we need to sum up the finance charges for each month.

Let's take a look at the finance charges listed for each month:

1. Month 1: \[tex]$0.00 2. Month 2: \$[/tex]33.00
3. Month 3: \[tex]$32.84 4. Month 4: \$[/tex]32.67
5. Month 5: \[tex]$32.51 6. Month 6: \$[/tex]3.34
7. Month 7: \[tex]$32.18 Now, let's add these values together: \[ 0.00 + 33.00 + 32.84 + 32.67 + 32.51 + 3.34 + 32.18 \] Adding these amounts step-by-step: \[ 0.00 + 33.00 = 33.00 \] \[ 33.00 + 32.84 = 65.84 \] \[ 65.84 + 32.67 = 98.51 \] \[ 98.51 + 32.51 = 131.02 \] \[ 131.02 + 3.34 = 134.36 \] \[ 134.36 + 32.18 = 166.54 \] Therefore, the total amount of interest paid over the 7 months is \(\$[/tex] 166.54\).

Hence, the correct answer is:
D. [tex]\( \$ 195.54 \)[/tex]
