dimaraw [331]

{4x - 5y = 17

{x - 5y = 8

{x = 5y + 8

{4(5y + 8) - 5y = 17

{x = 5y + 8

{20y + 32 - 5y = 17 | - 32

{x = 5y + 8

{15y = -15 | : 15

{y = -1

{x = 5 * (-1) + 8

{x = 3

{y = -1

I put $500 in the bank. I now have $5000in the bank. Every year my money increased by 5%. How long that it takes?

Mashutka [201]

Answer:

It takes 47.19 years

Step-by-step explanation:

Your amount on the bank is given by the following equation:

$P(t) = P(0)(1+r)^{t}$

In which P(t) is your current amount, P(0) is the initial amount, r is the rate it changes, and t is the time since the money has been put on the bank.

I put $500 in the bank.

This means that $P(0) = 500$
