7 0

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:

$n = {10}^{4}$

lions [1.4K]

In the question it is given that,

The students at Midtown Middle school sold flowers as a fundraiser in September and October. In October, they charged $1.50 for each flower

And the October price was a 20% increase of the September price.

Let the price of the flower in October be $x

So we have

$x+ \frac{20}{100}x = 1.50 \\ \frac{120x}{100} = 1.50 \\ x = \frac{1.50*100}{120} = 1.25$

So the price of the flower in Septembet is $1.25 .
