(d)
Graph is attached
Step-by-step explanation:
we are given
It costs $145 for 10 people to attend a concert
(a)
Number of people =10
Total cost =145
now, we can find constant proportionality
k= ( total cost)/(number of people)
(b)
Let's assume
cost is C
number of people as x
so, we can set equation as
now, we can plug value
(c)
we can plug x=8
C=116
So,
the cost of 8 people is $116
(d)
we can draw graph
