You mark it up 20% Price + 20% = p + 20/100p = p (1 + 0.20 ) = 1.2 p
6.45 * 1.2 = 7.74
You take off 5% which by the same reasoning (almost) means p/1.05
7.74 / 1.05 = 7.37
Now you need a sales tax
7.37 * 1.06 = 7.81 dollars.
Answer: The customer paid 7.81 <<<<=====

D please give brainliest
Step-by-step explanation:
Y intercept of a function can be obtained by evaluating the value of the function when x=0, i.e.
y-intercept of f(x) = f(0)
Here, f(x) = 4^(x)
so y-intercept = f(0) = 4^0 = 1
7 is 1/10 of 70 because 7 can go into 70 10 times
