a) 6.8%
b) 7.8%
c) 78%
d) 680%

6.8%

Step-by-step explanation:

We need to find both percentage so we can determine the increase.

Finding percentage of $10 return: 1% return

Finding percentage of $78 return: 7.8% return

To find the percent increase we do 7.8%-1.0% = 6.8%

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
