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.
For this case we have the following equations:
y = 60x + 40
y = 50x + 80
Equaling both equations we have:
60x + 40 = 50x + 80
From here, we clear the value of x:
60x - 50x = 80 - 40
10x = 40
x = 40/10
x = 4 weeks
Substituting x = 4 in any of the equations we have:
y = 60 (4) + 40
y = 240 + 40
y = 280 $
Answer:
$ 280 4 weeks
