Walt made an extra $10,000 last year from a part time job. He invested part of the money at 2% and the rest at 3.75%. He made a total of $270.00 in interest. How much was invested at 2%? Walt invested $ at 2%?

$4000

Step-by-step explanation:

.0375x + .02(10000-x) = 270

.0375x + 200-.02x = 270

.0175x + 200 = 270

.0175x = 70

x = 70/.0175

x = $4000 (answer)

 First three terms are 1/25, 1/5, and 1 in that order.

Explanation:

The fifth term is 25, which makes the fourth term to be 25*(1/5) = 5. We multiply any term by the reciprocal of the common ratio to move back to the previous term.

The third term is 5*(1/5) = 1. The second term is 1*(1/5) = 1/5. The first term is (1/5)*(1/5) = 1/25

Therefore, the first five terms are:

1/25, 1/5, 1, 5, 25

As we move from left to right, we multiply each term by 5. Going in reverse, we multiply by 1/5.
