400 - 175 = 225
0.15x = 225
x = 225/0.15
x = 1500
0.15x = 225
x = 225/0.15
x = 1500
job2 = 175 + .15s , where s is sales
when are they equal?
175 + .15s = 400
.15s = 225
s = 225/.15 = 1500
notice the solution to the equation contains all the calculations that Ms Sue has also given you.
Let's assume Julie needs to sell "x" amount in order for the second job to pay as much as the first job.
For the first job, she earns a fixed amount of $400 per week.
For the second job, she earns a base salary of $175 per week plus a 15% commission on her sales. In mathematical terms, the amount she earns would be $175 + 0.15x (where x represents the amount she needs to sell).
We can set up an equation to solve for x:
$400 = $175 + 0.15x
To solve this equation, we first subtract $175 from both sides:
$400 - $175 = 0.15x
Simplifying further:
$225 = 0.15x
Now, we can isolate x by dividing both sides of the equation by 0.15:
$225 / 0.15 = x
x ≈ $1500
Therefore, Julie would need to sell approximately $1500 in order for the second job to pay as much as the first job.
