Final answer:
To find the sales amount that will result in the two options having the same weekly salary, set up an equation with the two salary options and solve for the sales amount.
Step-by-step explanation:
To find the sales amount that will result in the two options having the same weekly salary, we can set up an equation to represent each salary option and solve for the sales amount.
Option 1: Weekly Salary = $300 + 0.04(sales)
Option 2: Weekly Salary = $100 + 0.075(sales)
Setting these two equations equal to each other, we get:
$300 + 0.04(sales) = $100 + 0.075(sales)
Simplifying the equation:
$200 = 0.035(sales)
Dividing both sides by 0.035, we find:
sales = $200 / 0.035 = $5714.29
Therefore, the sales amount that will result in the two options having the same weekly salary is approximately $5714.29.
