Jen gets paid $150 per day plus 9% commission on the items she sells. How much will she have to sell to earn at $249?

Question

I'm having trouble solving a few math problems. Need help with one of them. Please help!

Answer 1

Hello, thank you for taking the time to post your question!

The idea here is that she needs to make

$249 - $150 = $99 on commission in order to hit this amount

Since commissions are 9% you can divide to get to the end value

$99 / 0.09 = $1,100

That means Jen will have to sell $1,100 to earn a total of $249

I hope that helps get you moving in the right direction! Feel free to reach out if you have any additional questions beyond that :)

Answer 2

We can set up an equation for the money Jen makes as a function of the number of items she sells:

 

y = 150 + 0.09x

 

We can plug in 249 for y and solve for x:

 

249 = 150 + 0.09x

99 = 0.09x

1100 = x

 

She has to sell $1100 worth of items to earn $249.
