If the population decreases with a constant rate of change and the decrease is 7% in the first year, what will the town's popula

Alexus [3.1K]

Given that the population of a town today is 33,000 people.

If the population decreases with a constant rate of change and the decrease is 7% in the first year.

The decrease in the population of the town in the first year is given by 0.07 x 33,000 = 2,310

The decrease in the population of the town in 6 years is given by 2,310 x 6 = 13,860

Therefore, in 6 years, the town's population will be 33,000 - 13,860 = 19,140

Theo has $5 more than Denise and Denise has $11 more than Rudy. Together they have $45. How much money does Denise have?

Blizzard [7]

Let
x------> amount of money Theo has
y------> amount of money Denise has
z------> amount of money Rudy has

we know that
x+y+z=$45-----> equation 1
x=5+y-----> equation 2
y=11+z----> equation 3

substitute equation 2 in equation 1
[5+y]+y+z=45-------> 2y+z=40-----> equation 4

y=11+z----> equation 3
2y+z=40-----> equation 4

resolves the equations system
using a graph tool
see the attached figure

the solution is
y=17
z=6
x=5+y----> x=5+17----> x=22

the answer is
<span>Denise has $17</span>
