Hey there! :)
To find mean, you have to add all the numbers and divide it by how many numbers there are.
70 + 68 + 72 + 66 + 68 + 69 + 66 + 71 + 74 + 66 = 690
There are 10 numbers
690 ÷ 10 = 69
Mean ⇒ 69

The answer would be 6 million, or 6,000,000.

From least to greatest, it would be
so say the number he's thinking of is n, write n down, then he multiplies it by 5 which is 5n then he subtracts 60 from 5n, which is 5n-60, the question states that the answer "5n-60" is equal to the number he started with which is n, so you setup 5n-60=n and solve for n.
