The table of the number of customers illustrates two different patterns
Deli should expect 90 customers to serve during week 8
<h3>How to determine the number of customers</h3>
From the table, the even number of week increases by 10, while the odd number of weeks reduces by 5.
At week 6, the number of customers is 80.
So, the number of customers at week 8 is:
Week 8 = Week 6 + 10
This gives
Week 8 = 80 + 10
Week 8 = 90
Hence, deli should expect 90 customers to serve during week 8

Suppose:
C=cost
c=cost per kilo-watt hour
w=number of watts
h=number of hours
thus
C=kwhc
where:
k=constant of proportionality:
k=C/(whc)
but
C=15 when w=6000, h=10/60=1/6 hours, c=7.5 cents per kw/h
thus
k=15/(6000*1/6*7.5)
k=0.002
thus:
C=0.002(whc)
hence:
when
h=70*2=140=140/6=70/3 hours the cost will be:
C=0.002(6000*70/3*7.5)
C=2100 cents
C=$21
