Using the graph, convert US$2 to ECS.

Solution

Looking at the graph provided, it appears to represent the conversion between United States dollars (US$) and Eastern Caribbean dollars (ECS). The horizontal axis (x-axis) represents ECS, while the vertical axis (y-axis) represents US$. The task is to convert US$2 into ECS using the graph.

Solution:

  1. Locate the value 2 on the US$ (y-axis).
  2. From this point, trace horizontally to the line representing the exchange rate.
  3. From the point of intersection with the line, trace vertically down to the ECS (x-axis).

From the graph:

  • US$2 corresponds to about 5 ECS.

So, US$2 is equivalent to 5 ECS.

Would you like more details or have any questions? Here are 5 related questions for further practice:

  1. How would you convert US$4 to ECS using the same graph?
  2. What is the approximate exchange rate (US$/ECS) based on the graph?
  3. How many US dollars would 8 ECS be equivalent to?
  4. If the rate changes, how would you reflect that on the graph?
  5. How do you interpret a graph where the conversion rate is not constant?

Tip: When working with conversion graphs, always double-check the axes and scales before reading values.
