Question

Consider the annual revenues of Samsung and Motorola as seen in the following table:

Let S(t) and M(t) represent the revenues of Samsung and Motorola, respectively, in billions of dollars, t years after 2000.

 A) Construct tables for (S+M)(t) and (S−M)(t). 

B) Evaluate (S+M)(8) and (S−M)(13) and explain what they mean in a sentence.

Answer 1

Hi Ximenia,

S+M- you would add the 2 together for each year.

S-M, you would subtract the motorola value from the samsung.

This app does not permit tables, but I can give you the values in an approximation of a table here.

Year S+M S-M

07 125 49

08 129 79

09 127 113

10 142 126

11 162 146

12 197 185

13 223 211

14 188 176

Part B is asking for specific values, the sum in 2008 which is 129 and the differences in 2013 which is 211.

this means the total revenue for both in 2008 was 129 and the difference in revenue in 2013 was 211.

Hope this helps, feel free to respond with a follow up question.
