Question: (Graph photo attached)
1 answer:
The double bar graph shows the number of imports and exports for a company in a certain week.
On how many days was the number of exports greater than the number of imports?
Answer: From the given double bar graph, we clearly see:
Number of imports for a company on Monday = 15
Number of exports for a company on Monday = 7
Number of imports for a company on Tuesday = 18
Number of exports for a company on Tuesday = 9
Number of imports for a company on Wednesday = 14
Number of exports for a company on Wednesday = 14
Number of imports for a company on Thursday = 15
Number of exports for a company on Thursday = 6
Number of imports for a company on Friday = 9
Number of exports for a company on Friday = 19
From the above information, we clearly see that only on Friday the number of exports are greater than number of imports. Therefore, there is only 1 day when the number of exports greater than the number of imports.
Hence the option D. 1 is correct

Hello,
to find the total cost (c) of the colored strips we have to multiply the number of strips (n) by the cost of each color strip (99¢), that as an algebraic function is:
[¢]
Now, if we use 3 solid color strips, that means that we use 4 patterned strips, so:
Answer: c=n*99 and Cost per curtain= $7.97
