Hi !

What a self improvement for a busy person who had difficulty finding time to exercise ?

-  scheduling daily invitation activity

answer; /// i believe that the correct answer is (c); ///when the lungs expand, they fill with air from the atmosphere;

      x/140 = 25/100

we need to find the x to find the x multiply 140 and 25

and what do you get 3500.   and what is 3500 divided by 100

= 35
