Final answer:
Kayla needs to sell more than $4425 to reach her weekly budget.
Step-by-step explanation:
The correct interpretation of the situation is that Kayla needs to sell more than $4425 to reach her weekly budget.
To find this, we first need to calculate Kayla's commission. Since she makes $105 per week, her commission on merchandise would be 20% of her total sales. Let's call her total sales 'x'. So her commission would be 0.2x.
Now, we can set up an equation to determine the minimum amount she needs to sell to reach her weekly budget:
$105 + 0.2x = $990
Simplifying the equation, we get:
0.2x = $990 - $105
0.2x = $885
x = $885 / 0.2
x = $4425
Therefore, Kayla needs to sell more than $4425 to reach her weekly budget.
