Congrats on making it to integrals!
Basically you need to integral your function because integral rate in respect to time = total amount.
Also your bounts are (2001-1990,2006-1990)=(11,16)

Thus we take integral like:
int(11,16)(928.5e^(0.0249x))=
(11,16)928/0.0249e^(0.0249(x))-928/0.0249e^(0.0249(x))
(You can check this by taking its derivative and seeing if you get the original function)
928/0.0249e^(0.0249(16))-928/0.0249e^(0.0249(11))=6498.1

Help please ughhhhhhhh

=P*r*t
=500*4.5%*10
=225
p= 500
r= 4.5%
t= 10

13+x+195=13(x+15)...

LUCKY_DIMON [66]

First, let's expand the right side. Now our equation is

$13+x+195=13x+195$

Now, we gather all the terms with x in it on the left side, and the numbers without x on the right. We get:

$-12x=-13$

And then we can make this

$12x=13$

We divide both sides by 12 to get x on its own, so x = 13/12 or 1.08
