Answer: $1764.88 is a good estimate of his monthly expenses.
Step-by-step explanation:
Since we have given that
Rent charges = $1258
Phone charges = $46.88
Groceries per week = $115
Number of weeks in a month = 4
So, Total groceries charges in a month is given by
\(115\times 4\\\\=\$460\)
So, total good estimate of monthly expenses would be
\(\$1258+\$46.88+\$460\\\\=\$1764.88\)
Hence, $1764.88 is a good estimate of his monthly expenses.
