To solve this problem, we need to determine the value of x, which represents the amount of money Jill makes per day in her first month working online.
Let's break down the information given:
Amount of money Jill makes per day in her first month: x
Amount of money Jill makes per day in her second month: 2x
Amount of money Jill makes per day in her third month (working every other day): 2x
Total amount of money Jill makes over three months: $1200
We can set up the equation as follows:
(Number of days in first month * Amount of money per day in first month) + (Number of days in second month * Amount of money per day in second month) + (Number of days in third month * Amount of money per day in third month) = Total amount of money
(30 * x) + (30 * 2x) + (15 * 2x) = $1200
Let's simplify and solve for x:
30x + 60x + 30x = $1200
120x = $1200
To isolate x, we divide both sides of the equation by 120:
120x / 120 = $1200 / 120
x = $10
The value of x is $10.
#### 10
The answer is: 10
