Answer:
Cost for the 5 gift cards = $20
Step-by-step explanation:
In the given graph,
y axis shows the "total cost" in dollars
x axis shows the "number of gift cards"
According to the graph:
Cost of 1 card = $20
Cost of 2 cards = $40
Cost of 3 cards = $60
Cost of 4 cards = $80
We see that that relation represents the linear relation.
So, cost of 5 cards = 5*$20 = $100
That's the final answer.
I hope it will helps you.
