Exponential growth consistently raises the base amount/number to a certain degree. The above answers increase a digit by a number of percentage steadily over a period of time. 

Answer: Shasta increases the amount she saves each month by 5%.

The amount of cell phone subscribers in a small town increases by 75% each year.

The price of a stock goes up 12% each year.

Step-by-step explanation:

The exponential growth happens when a given quantity increases by the constant rate of proportion in each given time period.

  • Shasta increases the amount she saves each month by 5%.

This is an example of exponential growth with rate of increase 5%.

  • The population over the last decade of the Black Rhino is such that it is nearing extinction.

This shows decrease in population , so this cannot be example of exponential growth.

  • A tennis tournament starts with 64 participants. Each round, half the players are eliminated.

This shows decrease in participants , so this cannot be example of exponential growth.

  • The amount of cell phone subscribers in a small town increases by 75% each year.

This is an example of exponential growth with rate of increase 75%.

  • The price of a stock goes up 12% each year.

This is an example of exponential growth with rate of increase 12%.

A college used a $5,000 gift from an alumnus to make two student loans. The first was at 5% annual simple interest to a nursing student. The second was at 7% annual simple interest to a business major. If the college collected $310 in interest the first year, how much was loaned to each student?

Answers

Hello,

Let x the amount allocated to the 1 student
Let y the amount allocated to the 2 student

x+y=5000
5/100 *x +7/100 * y =310

==>
5x+7y=31000 (1)
x+y=5000 (2)
(1)-5*(2)==>
2y=6000 ==>y=3000 and x=5000-3000=2000
Proof:
2000+3000=5000
5/100*2000+7/100*3000=100+210=310
