Answer:
- Lisa: 22
- Chau: 14
- Austin: 88
Step-by-step explanation:
The given relations can be used to describe each of the numbers in terms of how many Lisa served. Those can then be related by the total served.
__
<h3>setup</h3>
Let L represent the number of orders Lisa served. Chau served 8 fewer, so (L -8). Austin served 4 times as many, so (4L). The total served was ...
L +(L -8) +4L = 124
<h3>solution</h3>
6L = 132 . . . . . . . . add 8, combine terms
L = 22 . . . . . . . . divide by 6
L -8 = 22 -8 = 14 . . . the number Chau served
4L = 4(22) = 88 . . . the number Austin served
The numbers each served were ...
- Lisa: 22
- Chau: 14
- Austin: 88
