Answer:
Step-by-step explanation:
At the self employed store, her monthly expense would be 
y = $835
Which would plot as a horizontal line
At the franchise store here expense would be 
y = 5x where x is the number of haircuts completed.
This would plot as a straight line of slope 5
The two would intersect when the two y values are equal
5 x = 835
so the same cost per month would occur at y = 835 
at the franchise, she would have completed 835/5 = 167 haircuts.
If she plans on doing fewer than 167 haircuts per month, she nets more money at the franchise, 
If she completes more than 167 haircuts per month, the self employed store deal keeps more money in her pocket.
 
        
             
        
        
        
Answer:
6
Step-by-step explanation:
You have a total of $30, but you can't spend it all on buckets of balls because first you have to pay the fee to attend the golf clinic.
So you have to figure out how much you have left after you spend $12 on fees.
$30−$12=$18
This means that you can spend $18 on buckets of golf balls.
At $3 each, how many buckets can you buy with $18?
18÷3=6
This means that you can buy 
<u>6</u> buckets of golf balls at the clinic after paying the fee to join.
Equation: 
12+3x=30 
3x=18
x=6
