7. For homework Javier has to solve the equation below.
cricket20 [7]

Answer:

C 10⁴

Step-by-step 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 =  \frac{7750000}{775}

He can now easily simplify to get:

n = 10000

We rewrite as a power to get:

n =  {10}^{4}
