Answer:

  • Barbara: $269/week
  • Melinda: $147 per week

Step-by-step explanation:

Let b represent the amount Barbara earns. Then Melinda earns b-122, and the sum is ...

  b + (b-122) = 416

  2b = 538 . . . . . . . . add 122, collect terms

  b = 269 . . . . . . . . . divide by 2; Barbara's earnings

  (b-122) = 147 . . . . . Melinda's earnings

Barbara earns $269 per week; Melinda earns $147 per week.
