Answer
The cook's salary is $\$1840$
The custodian's salary is $\$3680$
The bus driver's salary is $\$2760$
Work Step by Step
Let the three salaries be $2x, 4x,$ and $3x$
We can find the value of $x$:
$2x+4x+3x = \$8280$
$9x = \$8280$
$x = \frac{\$8280}{9}$
$x = \$920$
The cook's salary is $(2)(\$920)$ which is $\$1840$
The custodian's salary is $(4)(\$920)$ which is $\$3680$
The bus driver's salary is $(3)(\$920)$ which is $\$2760$
