Answer:
A camera is discounted by $7.50 off its original price and had a 15% markdown.
Let the original price be represented as x
The solution proceeds as follows:
=>
=> x = 8.82
The actual original price comes to $8.82.
A student used the equation:
15(7.5) = Original price
and calculated the camera's original price to be $112.50.
This calculation was incorrect. The student mistakenly calculated 15% of the selling price instead of the original price.
He should have calculated 15% of the original price to equal the selling price.

Step-by-step explanation:
Greetings!
As illustrated in the diagram, the point you seek is where the two lines intersect.
This intersection point is found by solving the system of linear equations (both equations must be satisfied by the point):
You can approach solving it using the substitution method:
Then substitute x1 into equation 2 to resolve x2:
After which, utilize the x2 value to establish x1:

A fraction is deemed equivalent if it maintains the same value when expressed in simplest terms. The equivalent to is found in the chosen option;
First, halve both the numerator and denominator by 2
Then reduce further
2/2 = 1 and 6/2 = 3; Thus;
Next, multiply both the numerator and denominator by 3
