Question

Allison works in a department store selling

clothing. She makes a guaranteed salary of $350
per week, but is paid a commission on top of her
base salary equal to 15% of her total sales for the
week. How much would Allison make in a week in
which she made $300 in sales? How much would
Allison make in a week if she made xx dollars in
sales?

Answer 1

a. $395

b. $(350 + 0.15x)

Explanation:

Her income in a week can be written as;

$350 + 15% of sales

a. In the case of $300 sales in a week

Mathematically, that would be;

$350 + 15% of $300

$350 + (15/100 * 300)

$350 + $45 = $395

b. In the case of $x in sales

= $350 + 15% of x

= $350 + (15/100 * x)

= $350 + 0.15x

= $(350 + 0.15x)
