he Gonzales family drove 300 miles on the first day of their vacation and 250 on each day after that. Let d represent the number of days they drove after the first day. Which expression gives the total distance they drove? A. 250 + 300d B. 250 + d + 300 C. + 300 D. 250d + 300

OpenStudy (genericnoodles):

This one is easy. They drove 250 miles every day, do you know how to explain that mathematically?

OpenStudy (jameshorton):

nope

OpenStudy (jameshorton):

c is d/250+300

@LynFran

OpenStudy (dan815):

lets d be the number of days after the first day Total distance = 300 + 200 * d

OpenStudy (jameshorton):

wat is the answer

OpenStudy (genericnoodles):

200*d can be written as 200d and still mean the same thing, for future problems :)

OpenStudy (jameshorton):

wat he said was wrong

OpenStudy (genericnoodles):

Exactly what he just said, that's the answer.

OpenStudy (genericnoodles):

Sure about that?

OpenStudy (jameshorton):

none of them start off with 200 it only start off with 250

OpenStudy (genericnoodles):

Just read what he said and apply it to your answers :)

OpenStudy (jameshorton):

@hoots89

OpenStudy (jameshorton):

it wont let me it only 250 it not no 300

OpenStudy (genericnoodles):

what grade are you in?

OpenStudy (jameshorton):

6th

OpenStudy (genericnoodles):

300+250d is the same exact thing if you switch the numbers. So 250d+300. I still feel like you don't understand but I don't know how to explain it further. Good luck.
