Boy, you get those easy problems in grade 7. We used to get much more difficult problems at that level. These are just simple multiplication. Note the numbers and multiply them. You should be able to do so. Begin to do and spend less time on the internet:)

do your self

we should not give you answers to your homework, you should find your self!

First step in solving such problems is to write what you know, and what you do not know. The following are tips. I will not write the problem for you.

1) km = d * 8 (this is the first equation), you should be able to get it from here.
2) everyone has to pay 100, no matter how many months they are so what you add. You are proportional to the number of months by the cost per month.
3) How many babies were born one minute
4) How many are there mintes an hour, how many hours a day are both proportional mins hours, how many days a week multiply that times in minutes per day
