ANSWER
If Whitney performed 290 haircuts in a month, she would pay $580 to either salon.
Step-by-step explanation
She has two options of rent:
• Self-employment: $580 of rent to the salon monthly
,
• Franchise: $2 per haircut
Let x be the number of haircuts Whitney does in a month. Independently of the number of haircuts, the Rockport Salon's rent is always $580. If she does x haircuts in the franchise, the cost of rent is $2x.
We have to find for how many haircuts, the rent is the same for both, so we have to solve the equation,
Divide both sides by 2,
Hence, if she performs 290 haircuts, the rent for both places will be the same, $580.
