Let, after t hours costs are the same.
Mathematical equation of charges taken by first studio :
Mathematical equation of charges taken by second studio :
So,
Therefore, after 6.964 hours cost of both studio is same.
Hence, this is the required solution.

b-6+4=10
When it doesn’t look like a U anymore and is upside down
Looking at an equation than when x is negative
Answer:
It would have to be 25 dimes
Step-by-step explanation:
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
On the other hand we have that if two lines are perpendicular, then the product of their slopes is -1. So:
The given line is:
So we have:
We find
So, a line perpendicular to the one given is of the form:
We substitute the given point to find "b":
Finally we have:
In point-slope form we have:
