I think of a number, then divide by 8, then add 73. If the result is 185, what number
did I first think of?

I'm not a math expert but I was able to figure this out Somehow .  the answer is 896.

Step-by-step explanation:

Sounds crazy but trust me the answer is 896. I did the math on a calculator, and im looking through the history.

50 miles

Step-by-step explanation:

let the distance of the trip be x

70% of x = 35

70/100 × x =35

70x / 100 = 35

cross multiply

70x =3500

Divide bothside by 70

70x/70= 3500/70

x =50

Therefore the distance of the journey is 50 miles.
