Step-by-step explanation:</h2>
The total number of students selected from both universities can be found as:
![f(x)+g(x)](https://tex.z-dn.net/?f=f%28x%29%2Bg%28x%29)
Where:
represents the number of students selected from university A
represents the number of students selected from university B
represents the number of days of the fair.
So:
grouping terms:
![h(x)=(4x+2x)+(8+5) \\ \\ Solving: \\ \\ h(x)=6x+13](https://tex.z-dn.net/?f=h%28x%29%3D%284x%2B2x%29%2B%288%2B5%29%20%5C%5C%20%5C%5C%20Solving%3A%20%5C%5C%20%5C%5C%20h%28x%29%3D6x%2B13)
The graph of the function is shown below and you can realize that the solution is a linear equation.
Answer:
75
Step-by-step explanation:
![\frac{27}{45}=\frac{45}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B27%7D%7B45%7D%3D%5Cfrac%7B45%7D%7Bx%7D)
![x=\frac{45^{2} }{27} =75](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B45%5E%7B2%7D%20%7D%7B27%7D%20%3D75)
Answer:
Sales tax is an increase in the price of the item while a discount is the decrease of the price. A 5% sales tax is an increase since your paying an extra 5% of the item price. 15% discount is a decrease since your now only paying 85% of the original price. Hope that helps

%error=100(estimated-actual)/actual
%error=100(96-(96-16))/(96-16)
%error=100(16/80)
%error=1600/80
%error=20%
She overestimated how many bracelets she would sell by 20%
