a total of 12 thousand passengers normally ride the green line of the mbta during the morning rush hour . the token prices for a ride are $1.05 for junior and high school students $2.10 for adults and &1.05 for senior citizens and the revenue from these riders is $23,100. If the token price were raised to $1.25 for junior and high school students and $2.40 for adults and the senior citizen price were unchanged the expected revenue from these would be $26,340. How many riders in each category normally ride the green line durning the morning rush hour?

I’d say letter a..

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 : )
