Julianne opens a dance studio. her start up costs for the building, advertising, and supplies total $52,000. each day, she spends $680 on operating costs (like utilities and wages). she earns $960 per day from her students' lesson fees. part a: write an equation or inequality to represent this situation. let d be the number of days. part b: when will julianne begin making profit? show all the work you did to arrive at your answer.

For this case we have:

Part A:

Since d is the variable that represents the number of days, we can represent an inequality for the gains given by:

Part B:

We want to know the moment from which Julianne obtains earnings, for that we clear d of the previous inequality:

To start making a profit, Julianne must work more than 186 days.

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
