Answer:
x+y=24 so we can say
x=24-y making 3x+5y=100 become
3(24-y)+5y=100
72-3y+5y=100
72+2y=100
2y=28
y=14, since x=24-y
x=10
So there are 10 3-point questions and 14 5-point questions.

Answer:
.
Step-by-step explanation:
It is given that,
Initial population of a town = 2000
Growth rate = 4% = 0.04 per year
The exponential growth function for population is

where,
is initial population, r is growth rate and t is number of years.
Substitute
in the above equation.


Therefore, the required equation is
, where P is population after t years.
