There is none except for eleven and that is it
Step-by-step explanation:
Let the required number be n
![\therefore \: \frac{90}{100} \times n = x \\ \\ \therefore \: \frac{9}{10} \\ \\ \therefore \:n = \frac{10}{9} x \\ \\ \therefore 100\% \: of\:n = \frac{10}{9} x \times 100\% \\ \\ = \frac{10}{9} x \times \frac{100}{100} \\ \\ = \frac{10}{9} x \\](https://tex.z-dn.net/?f=%20%5Ctherefore%20%5C%3A%20%20%5Cfrac%7B90%7D%7B100%7D%20%20%5Ctimes%20n%20%3D%20x%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20%5C%3A%20%20%5Cfrac%7B9%7D%7B10%7D%20%20%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3An%20%3D%20%5Cfrac%7B10%7D%7B9%7D%20x%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20100%5C%25%20%5C%3A%20of%5C%3An%20%3D%20%5Cfrac%7B10%7D%7B9%7D%20x%20%5Ctimes%20100%5C%25%20%5C%5C%20%20%5C%5C%20%20%3D%20%5Cfrac%7B10%7D%7B9%7D%20x%20%5Ctimes%20%5Cfrac%7B100%7D%7B100%7D%20%20%5C%5C%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B10%7D%7B9%7D%20x%20%20%5C%5C%20)

Answer:
a) On average, homes that are on busy streets are worth $3600 less than homes that are not on busy streets.
Step-by-step explanation:
For the same home (x1 is the same), x2 = 1 if it is on a busy street and x2 = 0 if it is not on a busy street. If x2 = 1, the value of 't' decreases by 3.6 when compared to the value of 't' for x2=0. Since 't' is given in thousands of dollars, when a home is on a busy street, its value decreases by 3.6 thousand dollars.
![t(x1, 0)= 24.6 + 0.055x1\\t(x1, 1) = 24.6 + 0.055x1 - 3.6\\t(x1, 1) = t(x1, 0) - 3.6](https://tex.z-dn.net/?f=t%28x1%2C%200%29%3D%2024.6%20%2B%200.055x1%5C%5Ct%28x1%2C%201%29%20%3D%2024.6%20%2B%200.055x1%20-%203.6%5C%5Ct%28x1%2C%201%29%20%3D%20t%28x1%2C%200%29%20-%203.6)
Therefore, the answer is a) On average, homes that are on busy streets are worth $3600 less than homes that are not on busy streets.
Answer:
72 adult tickets were sold and 114 child tickets were sold.
Step-by-step explanation:
x+y=186, 14x=10y=2148
x=186-y
14(186-y)+10y=2148
2604-14y+10y=2148
2604-4y=2148
-4y=-456
y=144
x=186-144 : x=72
