Answer:
$7,056.83
Step-by-step explanation:
Rewrite given data in the following table:
[tex]\begin{array}{ccc}\text{Operation}&\text{Amount}&\text{Mathematical operation}\\\text{Beginning balance}&\$9,145.87$\\\text{Made deposit}&\$2,783.71&"+"\\\text{Wrote checks}&\$4,871.90&"-"\\\text{Paid a maintenance fee}&\$12&"-"\\\text{Earned interest}&\$11.15&"+"\end{array}[/tex]
To find the balance at the end of the month, complete all mathematical operations:
[tex]\$9,145.87+\$2,783.71-\$4,871.90-\$12+\$11.15=\$7,056.83[/tex]
