Question

The graph shows the cost of gold as a function of its

amount. Use the graph to determine the cost (in dollars) of
15.0 g of gold.
Gold Cost ($)
800
600
400
200
5
10
Amount (g)
15
20

Answer 1

If it’s 15g of gold it would be $600

Answer 2

The cost of 15.0 g of gold is $600.00.

The graph shows a linear relationship between the cost of gold and its amount. This means that the cost of gold increases in a straight line as the amount of gold increases.

To determine the cost of 15.0 g of gold using the graph, we need to find the point on the graph where the amount is 15.0 g and then read the corresponding cost value on the y-axis.

Starting at the bottom of the graph, we can see that the cost of 0 g of gold is $0.00. As we move up the graph, the cost increases linearly with the amount of gold. At 5.0 g of gold, the cost is $200.00. At 10.0 g of gold, the cost is $400.00. At 15.0 g of gold, the cost is $600.00.
