Alexander left his house at time zero and drove for 8 minutes to the store at a speed of 1 block every 4 minutes. Then he stopped and went into the store for 7 minutes. From there, he drove in the same direction at a speed of 1 block per minute until he got to the bank, which is 2 blocks away from the store. He stopped at the bank for 2 minutes. Then he drove home at a speed of 2 blocks every minute. Make a graph of showing the number of blocks away from home that Alexander is x x minutes after he leaves his house, until he gets back home.

Were is the problem

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 : )

Iam not sure but i think the answer is b
