Answer 1

As the graph shows the cost of apples at a local market, Use the graph to answer problems 1-3

Part 1)

What is the cost of 1 apple and of 3 apples? How do you know?

Answer:

From the given graph which shows the cost of apples at a local market, it is clear that:

When we buy 1 apple, the cost is indicating 0.5+ (0.5/2) = 0.5+0.25 = $0.75

We know because x-axis is representing the number of apples and y-axis is representing the cost.

Therefore, when the number of apples is 1 on x-axis, then the cost is showing $0.75 on y-axis.

also

when we buy 3 apple, the cost is indicating 2+ (0.5/2) = 2+0.25 = $2.25

We know because x-axis is representing the number of apples and y-axis is representing the cost.

Therefore, when the number of apples is 3 on x-axis, then the cost is showing $2.25 on y-axis.

Part 2)

What does the point (0, 0) represent in this context?

• The (0, 0) represents the origin of the graph.

It means that the cost will be zero US dollars if you do not buy any apple. In other words, for 0 number of apples, the cost will be $0.

Part 3)

What does the point (2, 1.5) represent in this context?

The (2, 1.5) represents that when you buy 2 apples, the cost for buying 2 apples will be $1.5.

We know because x-axis is representing the number of apples and y-axis is representing the cost.

Therefore, when the number of apples is 2 on x-axis, then the cost is showing $1.5 on y-axis.
