Steven's school is selling chocolate bars to earn money for new band instruments. The school will receive 33% of the total sales revenue, y, given by the model y = 0.33x, where x represents the sales revenue. What is the meaning of the x-intercept in the model?

A) The x-intercept cannot be determined.
B) The x-intercept represents the school's percentage.
C) The x-intercept represents the sales revenue when no money was earned by the school.
D) The x-intercept represents the number of bars of candy sold.

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )

How many shares did he have to begin with?
