In average, your monthly income is $2,557.91
<h3>How much did you earn per month, on average?</h3>
We know that in the year you win a total of $30,694.95, and we want to know how much you win per month.
We know that in a year there are 12 months. To get how much you win, in average, in one of these months, you need to take the quotient between the total amount that you earn in one year, and the number of months in a year.
It gives:
N = $30,694.95/12 = $2,557.91
In average, your monthly income is $2,557.91

Answer:
B. 20
Step-by-step explanation:
x + 40 = 3x
x - x + 40 = 3x - x
40 = 2x
20 = x
X = 1st job
y = 2nd job
x + y = 22......x = 22 - y
7x + 8.25y = 171.50
7(22 - y ) + 8.25y = 171.50
154 - 7y + 8.25y = 171.50
-7y + 8.25y = 171.50 - 154
1.25y = 17.50
y = 17.50 / 1.25
y = 14 <== 14 hrs at the 8.25 per hr job
x + y = 22
x + 14 = 22
x = 22 - 14
x = 8 <=== 8 hrs at the 7 per hr job
