Answer:
Jason has $58.20 and Jeff has $13.80.
Step-by-step explanation:
Let x represent the amount of money Jason has, and y represent the amount of money Jeff has.
We know that together they have $72. So, we can write the following equation:

We know that Jason has three <em>more</em> than four <em>times</em> the amount of money Jeff has. So:

This is a system of equations. We can solve it by using substitution. Let's substitute the second equation into the first. This yields:

Combine like terms:

Subtract 3 from both sides:

Divide both sides by 5:

So, Jeff has $13.80
We know that Jason has three more than four times the amount of money Jeff has.
Therefore, Jason has:

Multiply and add:

So, Jason has $58.20 and Jeff has $13.80.
And we're done!
Answer: It is a statistic
Step-by-step explanation: It gives info
Xy = 72
x - y = 1
x = 1 + y
(1+y)y = 72
y + y^2 = 72
y^2 + y - 72 = 0
(y-8)(y+9) = 0
y = 8 , y = - 9
x = 1 + 8
x = 9
y = 8

<u>Answer:</u>
The available amount for the down payment of car and invested $3,200 at 3.75% interest compounded continuously is 3449.23$
<u>Explanation:</u>
We know final amount is given by
Where,

A = final amount
P = initial principal balance = $3200
r = interest rate = 3.74%
t = number of time periods elapsed = 2 years
Substituting the values in the formula

A=
We know, e = 2.72
So we get A = 3449.23$ which is the available amount for the down payment of car .
