Given:• The graph shows the history of the value of currency X in units of currency A and in units of currency B for the 12-week period beginning on 8 April.
• The graph has two plotted lines: one showing currency X’s value in terms of currency A and one showing currency X’s value in terms of currency B over time.
To Find:• Blank 1: The approximate time when the greatest value of currency X expressed in units of currency A occurred
• Blank 2: The approximate time when the greatest value of currency X expressed in units of currency B occurred
Solution:Approach:
• The y-axis label tells us that the graph shows the value of ONE unit of currency X in terms of currency A (blue line) as well as in terms of currency B (black line).
• For any line (blue/black), the
highest point represents when currency X had the
highest value in terms of currencies A/B.
• We will find this point visually and then just read the x-axis to get the date when it happens.
Blank 1:
• From the graph, the value of currency X in units of currency A (shown by the black line) reaches its highest point around early May.
• Among the given options (30 April, 4 May, 3 June), the peak occurs nearest 4 May.
Blank 2:
• From the graph, the value of currency X in units of currency B (shown by the blue line) reaches its highest point around late May/early June.
• Among the given choices (30 June, 1 June, 31 May), the peak occurs closest to 1 June.
