First we can divide it by 106 then multiply it by 100 to get rid of the 6% sales tax, which now the cost of the stuff is $17.50.
Next, we subtract 8 from this to represent the clothing pattern cost. Now it is $9.50.
The last stap to this is to divide it by 1 1/4 to get the final cost per yard:
The fabric costs $7.60 per yard. Hope this helps!
Answer:
x = 81
Step-by-step explanation:
using the rule of logarithms
x = n ⇒ x = 
given
x = 4 , then
x = 
= 81
I don't think this is possible...
But if you mean 9 then the root is 3
Subtract 45 on each side so it would be
0.15X=104 then divide both sides by 0.15X
then X= 700
