You evidence of how you got that answer

It’s a. The reason is because Beth makes a stable income for her first 20hrs of work, and then gets another constant income for her coming hours. That said this has to be a straight line followed by another straight line. That narrows it down to a and b. It can’t be b, because if it were Beth would be making less than she did before after her pay changes. Because she makes more, the graph showing this must be a

Sorry can u repeat that?

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 : )
