help me the is 25 points :) ty

Answer 1

C 10⁴

Explanation:

The given equation is

`7.75n = 77500`

Javier has to solve for n

He can multiply through by 100 to get;

`775n = 7750000`

He can now divide through by 775 to obtain:

`n = (7750000)/(775)`

He can now easily simplify to get:

`n = 10000`

We rewrite as a power to get:

`n = {10}^(4)`
