To determine the total amount of payments Norma has made over the 7 months, we need to sum up all the payments she made each month, as specified in the "Payment received" column of the table.
1. The payment received at the end of month 2 was [tex]$\$[/tex]66.00[tex]$.
2. The payment received at the end of month 3 was $[/tex]\[tex]$65.56$[/tex].
3. The payment received at the end of month 4 was [tex]$\$[/tex]65.12[tex]$.
4. The payment received at the end of month 5 was $[/tex]\[tex]$64.69$[/tex].
5. The payment received at the end of month 6 was [tex]$\$[/tex]64.26[tex]$.
6. The payment received at the end of month 7 was $[/tex]\[tex]$63.83$[/tex].
Now, let’s add these payments together:
[tex]\[
66.00 + 65.56 + 65.12 + 64.69 + 64.26 + 63.83 = 389.46000000000004

Therefore, the total amount that Norma has made in payments over the 7 months is:
[tex]\[
\boxed{389.46}
