The number of dime Jenna have is 15 and the number of quarter Jenna have is 35.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Every evening Jenna empties her pocket and puts pockets and puts her change in a jar.

At the end of the week, she counted her money.

One week she had 50 coins all of them were dimes and quarters.

When she added them up she had a total of $10.25.

Let d be the number of dimes and q be the number of quarters.

Dimes = $ 0.10

Quarter = $ 0.25

Then the equation will be

              d + q = 50 ...1

0.10d + 0.25q = 10.25  ...2

By solving equations 1 and 2, we have

d = 15 and y = 35

Then the number of dime Jenna have is 15.

Im stuck on this problem. Please explain how you got your answer​
klemol [59]

The function y=0.3^x represents exponential growth with the initial value equal to 1, the decay factor equal to 0.3, and the rate equal to 0.7.

<h3>Population Growth Equation</h3>

The formula for the Population Growth Equation is:

P_f=P_o*(1+\frac{R}{100}) ^t

           

Pf= future population

Po=initial population

r=growth rate

t= time (years)

growth or decay factor =  (1 ±r)

When 1+R  > 1, the equation represents growth, while 1+R < 1 the equation represents decay.

The question gives:

y=0.3^x, then

Pf=y

Po= 1  

(1+\frac{R}{100}) =0.3 , thus

(100+R}) =30\\ \\ R=-100+30\\ \\ R=-70

r= -70%= -0.7

decay factor= (1-0.7)=0.3

Therefore,

1+R will be = 1+(-0.7)=1 - 0.7 =0.3

When 1+R >1, the function represents exponential growth.
