Step-by-step explanation:
Let Jim earned $ x
Therefore, Debbie earned = $(x + 1600)
According to the given information:
![x + (x + 1600) = 7200 \\ \therefore \: 2x = 7200 - 1600 \\ \therefore \: 2x =5600 \\ \\ \therefore \: x = \frac{5600}{2} \\ \\ \therefore \: x =2800 \\](https://tex.z-dn.net/?f=x%20%2B%20%28x%20%2B%201600%29%20%3D%207200%20%5C%5C%20%20%5Ctherefore%20%5C%3A%202x%20%20%3D%207200%20-%201600%20%5C%5C%20%5Ctherefore%20%5C%3A%202x%20%20%3D5600%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20%5C%3A%20x%20%20%3D%20%5Cfrac%7B5600%7D%7B2%7D%20%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20%5C%3A%20x%20%20%3D2800%20%5C%5C%20)
Thus, Jim`s earning = $2800
Debbie`s earning = 2800 + 1600 = $4400

Answer:
<h3>132°</h3>
Step-by-step explanation:
If line PS has midpoint a Q and ray QR, then line PQS will be a straight line and <PQR + <RQS = 180 (sum of angle on a straight line).
Given
<PQR = 3x-6
<RQS = x+ 2
To get x, we will use the relationship above;
3x-6+x+2 = 180
4x-4 = 180
add 4 to both sides
4x-4+4 = 180+4
4x = 184
x = 184/4
x = 46
Since <PQR = 3x-6, we will substitute the value of x into the formula;
<PQR = 3x-6
<PQR = 3(46)-6
<PQR = 138-6
<PQR = 132°
Hence the size of angle PQR is 132°
