The number of people using an older version of a spreadsheet program decreases at a rate that is proportional at any time to the

Paraphin [41]

Answer:

5842 people after 2 months

Step-by-step explanation:

Given

Initial Value: $a =10000$

Rate: $r = 20\%$ every 6 months

Required

Number of people using it after 2 months

The function follows an exponential model.

So, we need to first write out the function.

If Rate: $r = 20\%$ every 6 months

Then

Rate: $r = 40\%$ after 1 year

$r = 0.04$

The function is represented as:

$y = ar^x$

So:

$y = 10000 * 0.04^t$

For 2 months, we have:

$t = 2\ months$

Convert to years

$t = \frac{2}{12}$

$t = 0.167$

$y = 10000 * 0.04^t$

$y = 10000 * 0.04^{0.167}$

$y = 5842$
