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}

gladu [14]
P = $70,  p = 2.5% = 0.025
q = 1 + 0.025 / 12 = 1.002
Future value of a periodic deposit:
A = P · q · ( q^30 - 1 ) / ( q - 1 )
A = 70 · 1.002 · ( 1.002^30 - 1 ) / ( 1.002 - 1 )
A = $2,166
Answer:
He will have $2.166 in 30 months.
