Question

the bar graph in the following graphic represents fictional net exports in billions of dollars for five countries. net exports are obtained by subtracting total imports from total exports; a negative net export means the country imported more goods than it exported. what is the sum of net exports for germany and china? a. -80 billion dollars b. 180 billion dollars c. 90 billion dollars d. 150 billion dollars

Explanation:

Step1: Determine Germany's net exports

From the bar - graph, Germany's net exports \(x=- 30\) billion dollars.

Step2: Determine China's net exports

From the bar - graph, China's net exports \(y = 120\) billion dollars.

Step3: Calculate the sum

The sum \(S=x + y\). Substitute \(x=-30\) and \(y = 120\) into the formula: \(S=-30+120\). Using the rule of adding integers \(a+(-b)=a - b\) (here \(a = 120\), \(b = 30\)), we get \(S=90\) billion dollars.

Answer:

c. 90 billion dollars
