Rosa has saved $490 in 6 weeks.
To find the answer to this, simply plug the number of weeks in for the value of x and solve.
f(x) = 250 + 40x
f(6) = 250 + 40(6)
f(6) = 250 + 240
f(6) = 490
There are a total of 297 students in the 7th grade. Rough estimates would say that about half of that number are boys and half are girls. Asking only 50 random girls would be biased because not only would it not be all of the girls (the number of girls would be around 148 or 149) but it would also be ignoring the roughly 148 to 149 boys there are on estimate. The sample would be biased because it would be ignoring the opinions of more than half the seventh grade.
