i need the formula for the following...
jennifer now earns $250 more than three times the salary she earned as a cashier. If she now earns $10,300 how much did she earn as a cashier?
thank you
Let x = her cashier's salary.
3x + 250 = 10,300
3350
$3350
Let cashiers salary be x
Cashiers salary = x
3x+250=10300 ( cuz she earns 10300 now )
3x =10300-250
3x= 10050/3
x= 3350
To find out how much Jennifer earned as a cashier, we need to set up an equation using the given information and then solve for the unknown.
Let's denote Jennifer's earnings as an unknown variable, say "x," when she worked as a cashier.
The problem states that Jennifer now earns $250 more than three times the salary she earned as a cashier, which can be expressed as:
Jennifer's current earnings = 3 * Jennifer's earnings as a cashier + $250
We are also given the information that Jennifer currently earns $10,300. Substituting these values into the equation, we get:
$10,300 = 3x + $250
Now, we can solve for "x," the amount Jennifer earned as a cashier.
First, subtract $250 from both sides of the equation:
$10,300 - $250 = 3x
This simplifies to:
$10,050 = 3x
Next, divide both sides by 3 to isolate "x":
$10,050 / 3 = x
Finally, perform the division to find Jennifer's earnings as a cashier:
x ≈ $3,350
Therefore, Jennifer earned approximately $3,350 as a cashier.
