Question

Christine, Tom, and Boris served a total of 89 orders Monday at the school cafeteria. Christine served 7 more orders than Tom. Boris served 2 times as many orders as Christine. How many orders did they each serve? ​

Answer 1

Tom=17 Christine=24 Boris=48

Explanation:

Christine=c

Tom=t

Boris=b

t+7+t+(t+7 times 2)=89

4t+21=89

4t=89-21

4t=68

t=17

c=t+7

c=17+7

c=24

b=2c

b=24(2)

b=48
