Question

Justin works in a department store selling clothing. He makes a guaranteed salary of $450 per week, but is paid a commision on top of his base salary equal to 30% of his total sales for the week. How much would Justin make in a week in which he made $2425 in sales? How much would Justin make in a week if he made x dollars in

Answer 1

We can convert that 30% into a decimal, as: 0.3 (That's 30/100)

Now, we can multiply this 0.3 by any quantity that we want to calculate 30% from.

For example, let's take Justin's commission:

`2425\cdot0.3=727.5`

Adding this to his base salary,

`450+727.5=1177.5`

We can conclude that Justin's paycheck for the week would be $1,117.5

Similarly, the expression for Justin's paycheck in a week were he made x dollars in sales is:

`0.3x+450`
