Answer:
yes
Step-by-step explanation:
This problem has some information which does not pertain to the answer. The sample size of 60 is not important to the answer. (Sample size is a concern when it comes to deciding if the survey results are valid!)
75% of the sample says they're going to college, so assuming that the same proportion of students in the entire school is going to college, you need to find 75% of 900.
900 x .75 = 675, the same as the counselor's determination.
Yes it is a rational number.
Answer:
Let x represent the amount of weeks she is saving up for the bike, and y represents the cost of the bike.
The equation would look like this:
So, let's say the bike costs $2000.
Divide 2000 by 20, and it will give you the x value (or, the amount of weeks it will take)
It will take 100 weeks for her to save $2000 for the bike, if she puts back $20 each week.
