Julianne opens a dance studio. Her start-up costs for the building, advertising, and supplies $52,000. Each day, she spends $650

Yuki888 [10]

The equation is: $960d-650d=52000$ and Julianne will begin making a profit after 168 days.

Explanation

Her total start-up cost is $52,000.

Each day, she spends $650 on operating costs (like utilities and wages) and she earns $960 per day from her students' lesson fees.

If the number of days to overcome the start-up cost is $d$ , then

the total operation cost spent in $d$ days $= \$650d$ and

the total students' lesson fees earned in $d$ days $= \$960d$

Part A: The equation to represent the situation will be: $960d-650d=52000$

Part B:  Julianne will begin making a profit when....

$960d-650d>52000\\ \\ 310d>52000\\ \\ d>\frac{52000}{310}\\ \\ d >167.741... \approx 168$

So, Julianne will begin making a profit after 168 days.
