Answer:

  • cook: $1840
  • custodian: $3680
  • bus driver: $2760

Step-by-step explanation:

There are a total of 2+4+3 = 9 "ratio units", so each one is worth ...

  $8,280/9 = $920

Multiplying the ratio by $920, we get ...

  cook : custodian : bus driver = $920 × (2 : 4 : 3) = $1840 : $3680 : $2760
