Answer:

42.9%

Step-by-step explanation:

So you would use [ ((V2 - V1) / |V1|) * 100 ]

V1 = 87.5 to V2 = 125

= ((125 - 87.5) / |87.5|) * 100

= (37.5 / 87.5) * 100

= 0.428571 * 100

= 42.8571% change

= 42.8571% increase

Then you round to 42.9!

Hope it helps! :)

Remember to use the change of base formula, which states that \log_a(b)=\frac{\log(b)}{\log(a)} so that everything has the same base of 10

The population of a school and is increasing at a rate of 2%per year;6yearsPLEASE HElp <br> Thanks
Shkiper50 [21]

Answer:

It can be modeled with the equation A=P(1.02)^6 but needs a starting population number to finish.

Step-by-step explanation:

To find the population in a future year, use the formula:

A = P (1+/-r)^t

where A is the amount, p is the starting population, r is 2% or 0.02, and t is the number of years.

Since the population is increasing it is addition. Substitute r=0.02 and t=6. Without a starting population, we cannot find the population in 6 years.

A = P (1+r)^t\\A=P(1+0.02)^6\\A=P(1.02)^6
