Answer:

$a_n = 1200(1.35)^n$

Step-by-step explanation:

Equation to remember:

$P_0(1+r)^t$ where t = time

$P_0$ = 1200 since that's the initial population

$r$ = .35 rate of change \\

$t$ = 5 years

Plug in the numbers;

$a_5 = 1200(1+.35)^5$

Since the prompt looks like it's asking for an equation given any number of years.. then just change 5 to n for number of years.

$a_n = 1200(1.35)^n$

If you received a 5% raise and your final paycheck was 100(which includes your 5% raise), how much was your original paycheck?

Schach [20]

so you were earning say "x", so "x" is the 100% of your paycheck.

but you're da bomb and so you got a raise of 5%, so the new amount of your paycheck is 100% + 5%, so is 105% really, and we happen to know that is $100.

$\bf \begin{array}{ccll} \$&\%\\ \cline{1-2} 100&105\\ x&100 \end{array}\implies \cfrac{100}{x}=\cfrac{105}{100}\implies 10000=105x \\\\\\ \cfrac{10000}{105}=x\implies 95.238\approx x$
