Answer:
-Annabel would make $1,220 in a week in which she made 2400 in sales
-The amount that Annabel makes in a week if she made x dollars in sales would be: $500+0.30x.
Explanation:
From the information given, you can calculate the amount Annabel makes in a week in which she made 2400 in sales by adding up her guaranteed salary per week plus the result of multiplying the total sales for 30%:
$500+($2,400*30%)=$500+720=$1,220
Now, the amount that Annabel makes in a week if she made x dollars in sales would be:
$500+0.30x, where x is the total amount of sales.
