$1km=1,000m\\1m=100cm\\therefore\\1km=1,000\cdot100cm=100,000cm\\----------------------\\\\15km=15\cdot100,000cm=1,500,000cm\\\\\boxed{1cm:15km\Rightarrow 1cm:1,500,000cm\Rightarrow1:1,500,000}\leftarrow scale\ of\ a\ map\\\\1cm\ of\ the\ map\ is\ equal\ 1,500,000cm\ of\ real\ distance\\1cm\ of\ the\ map\ is\ equal\ 15km\ of\ real\ distance$

For every one cm on the map that you measure, you count that as 15 km so if there is a mark 2.5 cm then you count that as 37.5km in real life

The last graph

Step-by-step explanation:

The problem presented here is similar to a compound interest problem since we have an initial value, a growth constant and the aspect of time.

We can consider the number of television sets currently produced by the company to be our Principal amount;

P = 2000

The rate of increase in production per month can be considered as our interest rate earned;

r = 25% = 0.25

The total number of television sets y will be our Accumulated amount;

A = y

The duration x becomes our time n.

The compound interest formula is given as;

$A=P(1+r)^{n}$

We simply substitute the given information into the formula;

$y=2000(1.25)^{x}$

This is an exponential growth function since the base of the exponent x is greater than 1.

A graph of the function will be an exponential curve passing through ( 0, 2000) since 2000 is our initial value
