Given:
The rate of interest on three accounts are 7%, 8%, 9%.
She has twice as much money invested at 8% as she does in 7%.
She has three times as much at 9% as she has at 7%.
Total interest for the year is $150.
To find:
Amount invested on each rate.
Solution:
Let x be the amount invested at 7%. Then,
The amount invested at 8% = 2x
The amount invested at 9% = 3x
Total interest for the year is $150.

Multiply both sides by 100.


Divide both sides by 50.


The amount invested at 7% is
.
The amount invested at 8% is

The amount invested at 9% is

Thus, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.

Answer:
I think b
Step-by-step explanation:
The probability that the larger of the two rolls was equal to 5 is; 2/9
<h3>Probability of possible outcomes</h3>
The total number of possible outcomes when the dice is rolled twice is 36 outcomes.
Now, for the larger of the two rolls to equal 5, the total number of favourable outcomes are 8 which are;
(1, 5), (2, 5), (3, 5), (4, 5), (5, 1), (5, 2), (5, 3), (5,4)
Thus, probability that the larger of the two rolls was equal to 5 is;
P(larger of 2 rolls equals 5) = 8/36 = 2/9
