Kira earns a $20 commission for every sale plus a base salary of $500. Her total income last week was $800. Which equation could be used to determine the amount of sales she had during that week.

Respuesta :

Answer:

800 = 500 + 20x

Step-by-step explanation:

Her base income is 500 so we start with

income = 500

Then she gets 20 per commission so lets set

x = commision

And since she gets 20 per commision that turns into 20x for the equation

So now the equation is

income = 500 + 20x

Last week she made 800 so

income = 800

therefore

800 = 500 + 20x
