Answer: 132
Step-by-step explanation: I just took the test
Local(L) = 1 x (15.99)
Online(O) = (1 x 13.99) + 6
So use that equation until you find the same number.
L1=15.99
O1=19.99
L2=31.98
O2=33.98
L3=47.97
O3=47.97
And your answer will be three from local and three from online.
She has to score at least 86 on her fifth test.
Further explanation:
We will use the average formula to find the fifth value.
Given
![Average\ required=80\\x_1=81\\x_2=73\\x_3=84\\x_4=76\\x_5=?](https://tex.z-dn.net/?f=Average%5C%20required%3D80%5C%5Cx_1%3D81%5C%5Cx_2%3D73%5C%5Cx_3%3D84%5C%5Cx_4%3D76%5C%5Cx_5%3D%3F)
We have to find x5
The formula for average is:
![x=\frac{Sum\ of\ values}{Total\ number\ of\ values}\\Here,\\n=5\\So,\\x=\frac{x_1+x_2+x_3+x_4+x_5}{5}\\Putting\ values\\80=\frac{81+73+84+76+x_5}{5}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7BSum%5C%20of%5C%20values%7D%7BTotal%5C%20number%5C%20of%5C%20values%7D%5C%5CHere%2C%5C%5Cn%3D5%5C%5CSo%2C%5C%5Cx%3D%5Cfrac%7Bx_1%2Bx_2%2Bx_3%2Bx_4%2Bx_5%7D%7B5%7D%5C%5CPutting%5C%20values%5C%5C80%3D%5Cfrac%7B81%2B73%2B84%2B76%2Bx_5%7D%7B5%7D)
