Answer:
Ali served 16 orders, Deon served 64 orders, Heather served 26 orders.
Step-by-step explanation:
Let order served by
Heather be h
Deon be d
Ali be a
We can write 3 equations from the word problem:
h + d + a = 106
d = 4a
h = 10 + a
We put 2nd and 3rd equation in first and solve for a:
h + d + a = 106
10 + a + 4a + a = 106
6a = 96
a = 16
Now,
d = 4a = 4(16) = 64
and
h = 10 + a = 10 + 16 = 26
Ali served 16 orders, Deon served 64 orders, Heather served 26 orders.
