Whenever you sign a lease for an apartment, you typically have to pay a security deposit in case you have caused any wear or tear on the apartment that has to be repaired before it can be re-leased. if no repairs need to be made, you get your entire deposit back. one apartment building has apartments that rent for $500 a month and security deposit of $700. the total cost c (in dollars) it costs to rent the apartment for m months is given by the function c=500m+700. graph the function and identify its domain and range. identify the domain and range if a renter only leases an apartment for one year and then moves out and doesn't get the security deposit back.

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 : )
