Answer:
Option A: 0.07c = 1.26 is the correct answer
Step-by-step explanation:
Given that the price of shirt is denoted by c.
Given that the sales tax is 0.07 times of the cost of shirt.
Mathematically it can be written as:
[tex]Sales\ tax=0.07c[/tex]
Now it is also given in the statement that the sales tax is $1.26
Putting this value in the above equation
[tex]1.26 = 0.07c[/tex]
As we have to find the cost, dividing both sides by 0.07
[tex]\frac{1.26}{0.07} = \frac{0.07x}{0.07}\\c = \frac{1.26}{0.07}[/tex]
Hence, we saw that the intermediate equation was: 1.26 = 0.07c
So,
Option A: 0.07c = 1.26 is the correct answer
