Answer: y = - 3 x + 500
Step-by-step explanation:
First, we will start off with y = since y is the amount of money left to spend.
Next, we see that three invitations cost $10. $10 / 3 = 3 . One invitation will cost $3
Lastly, we will create our final equation in slope-intercept form:
y = - 3 x + 500
<em> Side Note: We also could write something like y = -10(</em><em>) + 500 if we did not want to change the cost.</em>
