the cost of 8 people is $116
(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

Answer:
(8x + 100) litres
Step-by-step explanation:
According to the question,
- Given, In a village there are 8 water tanks to collect rainwater. On a particular day, x litres of rainwater is collected per tank. If 100 litres of water was already there in one of the tanks.
Therefore,
Number of water tanks = 8
Rainwater collected by each tank = x litres
∴ Rainwater collected by 8 tanks = 8x litres
But, 100 litres of water was already there in one of the tanks.
- So, the amount of water in the tanks = (8x + 100) litres
Let’s assume that Laura has x$
Jose = 8+ x
Keith= 3x
So the total is equal to
118= x + 8 +x + 3x
118= 5x + 8
Subtract 8 from both sides
110= 5x
Divide 5 by both sides
22$= x which is what Laura has
Jose will have :8+22= 30$
Keith will have :3*22=66$
