A = b√x+c
a/b = √x+c
(a/b)^2 = x + c
(a/b)^2 - x = c
X is 9 or c because -26-10 is -36 and -36/-4 is 9
Answer:B: 133.75$
Step-by-step explanation:
35 + 40 + 50= 125$
The total sales tax is 7%
We can put this into decimal form 7/100= 0.07
Because we want to just add 7% of the value back on we can also add 1 to that number
1.07
125 x 1.07 = 133.75
