Question

Josie selected a number n. She divided n by 2 and then subtracted 0.5 from the result. She took half of that result and then subtracted 0.5 to get the final result of 10. What is the value of n?

Answer 1

Your answer is N= Forty three

Answer 2

The answer is 43

to get this just do the problem backwards from 10 witch you would add .5 to get 10.5 and then multiply by 2 to get 21 then add .5 again to get 21.5 then you multiply it again by 2 to get the answer of 43

hope this helps GL
