z+9(8−x)+8(z+8)=
z+72-9x+8z+64=
9z-9x+136
<u> </u>
(3−10)^2−(5−12)^2 parenthesis first
(-7)²-(-7)²=
49-(49)=49-49=0
<u> </u>
2^2⋅4^3 exponent first
2*2*4*4*4
4*64=256
Te difference of 2 standard deviation of a population n1 & n2 is given by the formula:
sigma (difference)=√(sigma1/n1 + sigma2/n2), Plug:
sigma(d)= √(49/100 + 36/50)
Sigma(d=difference) =1.1
18 divided by 30 is 0.6. So I would say that B, or 0.6, is the correct answer.

Answer
If we had a sale price of 30% off of $1,050then the sale price is 70% of $1,050 or 0.7(1050) Then we add 7% sales tax to that making thefinal price paid 107% of [0.7(1050)] ... 1.07[0.7(1050)] = $786.45
