See below (I hope this helps!)
Step-by-step explanation:
Let's call the number of $8, $10 and $12 as x, y and z respectively. Then, we can write the following system:
x + y + z = 360 (1)
8x + 10y + 12z = 3500 (2)
x + y = 5z (3)
5z + z = 360 (Substitute (3) into (1))
6z = 360
z = 60
x + y = 5 * 60 (Substitute z = 60 into (3))
x + y = 300 (4)
8x + 10y + 12 * 60 = 3500 (Substitute z = 60 into (2))
8x + 10y = 2780 (5)
8x + 8y = 2400 (6) -- (Multiply (4) by 8)
2y = 380 (Subtract (6) from (5))
y = 190
x + 190 = 300 (Substitute y = 190 into (4))
x = 110
Answer: 12

Answer:
The outliers are 242 and 875
Step-by-step explanation:
Their numbers are far more away than the other numbers if you had it on a number line. Most of the numbers range from 480-510 (estimation of the range, sorry hehe), so the numbers that seem very far (almost excluded, I guess) would be the ones that are considered the outliers.
242 and 875 are over 100 spaces away from the other numbers, meanwhile 485,485,489,497,498,500,507,509 have shorter spaces in between.
