The number of people after n years is calculated through the equation,
An = (Ao)(1 + r)^n
where An is the population after n years, Ao is the initial population and r is the rate. Substituting the known values,
420 = (380)(1 + 0.03)^n
The answer is letter A.
Correct answer should be= 1.5 hours.
Answer:
0.8p or p - 0.2p
Step-by-step explanation:
You can find the price for any house minus the down payment by writing an expression with a variable. Let p be the price of the house. If you pay 20% then the price will be lowered by 20%. You will pay as your mortgage 80% of the price. You can write it as either the expression 0.8p or p - 0.2p.
So we are given two points, say P1(4,7), P2(x,19).
Slope is given by
m=3=(y2-y1)/(x2-x1)=(19-7)/(x-4)
solve for x
3=(19-7)/(x-4)
cross multiply
3(x-4)=12
3x-12=12
3x=12+12=24
x=8
Eight hundred and one point forty seven. Hope this helps!;)
