To determine the total amount that Benjamin has made in payments over the 7 months, we need to sum the individual payments he made at the end of each month.

Based on the credit card record provided in the table:

- At the end of month 1: Payment = [tex]$0.00 - At the end of month 2: Payment = $[/tex]48.00
- At the end of month 3: Payment = [tex]$47.80 - At the end of month 4: Payment = $[/tex]47.60
- At the end of month 5: Payment = [tex]$47.40 - At the end of month 6: Payment = $[/tex]47.20
- At the end of month 7: Payment = $47.01

We add these amounts together to find the total payments over the 7 months:

[tex]\[ 0.00 + 48.00 + 47.80 + 47.60 + 47.40 + 47.20 + 47.01 = 285.01 \][/tex]

Therefore, the total amount that Benjamin has made in payments over the 7 months is:

[tex]\[ \boxed{285.01} \][/tex]
