To find the average monthly mortgage payment over June, July, and August, we start by identifying the mortgage payments for each month.
From the given table:
- For June, the mortgage payment is $1200.00.
- For July, the mortgage payment is $1200.00.
- For August, the mortgage payment is $1200.00.
Next, we calculate the total mortgage payment over these three months:
[tex]\[ 1200.00 + 1200.00 + 1200.00 = 3600.00 \][/tex]
To find the average monthly mortgage payment, we divide the total mortgage payment by the number of months, which is 3:
[tex]\[ \text{Average Monthly Mortgage Payment} = \frac{3600.00}{3} = 1200.00 \][/tex]
Therefore, the average monthly mortgage payment is:
[tex]\[ \$1200.00 \][/tex]
