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 $\$2760$
