The graph shows the relationship between the total cost and the number of gift cards that raj bought for raffle prizes.

What would be the cost for 5 of the gift cards?

$80

$90

$100

$110

Answer : $100

The graph is attached below

From the graph we can see that,

When the number of gift cards = 1 then cost = $20

When the number of gift cards = 2 then cost = $40

When the number of gift cards = 3 then cost = $60

When the number of gift cards = 4 then cost = $80

The cost is increasing by 20 dollars for each card

Hence, cost = $100 for 5 of the gift cards.
