Answer:

Joe: 57
Scott: 19
Laura: 28

Step-by-step explanation:

Let s represent the number of orders Scott served. Then we have Joe served 3s, and Laura served (s+9). The total of orders served is ...

3s +s +(s +9) = 104

5s = 95 . . . . . . . . . . . subtract 9 and collect terms

s = 19 . . . . . . . . . divide by 5

3s = 3×19 = 57

s+9 = 19+9 = 28

Joe served 57 orders, Scott served 19, and Laura served 28 orders.

Step-by-step explanation:

Given:

Number of cookie batches Anna baked = 2

Number of cookies in each batch = c

Number of cookies Anna ate = 8

To Find:

An expression representing the number of cookies left with Anna
