Answer 1

carlos served 16 times dan served 64 times and karen served 9 times

Step-by-step explanation:

im just going to say 16 + 64 + 9 = 89

Answer 2

Answer:

Carlos = 16

Dan = 64

Karen = 9

Step-by-step explanation:

Let Carlos be x

Dan = 4x

Karen = x - 7

Their total is 89

Create an equation of Carlos + Dan + Karen = 89

x + 4x + x - 7 = 89

Combine like terms

6x - 7 = 89

Add 7 on both sides to get rid of 7

6x = 96

Isolate x by dividing by 6 on both sides

x = 16

Substitute the amount of orders each person served

Carlos = 16

Dan = 64

Karen = 9

Hope this helps :)

Have a great day!
