Joseph works two jobs to earn a bit of money during the summer. he mows lawns (x) with his dad’s company for $14/hr and he works at a daycare (y) for $12/hour. his schedule only allows him to work 46 hours per week over the summer. to cover phone bills, car insurance and gas, and adding $200 weekly into his savings, he must earn at least $500.

a) set up two inequalities to represent this scenario: (2 points)
hours he can work
$$$ he can earn

b) graph your system of inequalities (2 points)

c) if he worked 20 hours with his dad and 18 hours at the daycare, could he cover his monthly expenses? if yes, how much extra money does he earn? if no, how much is he short by? (2 points)

d) if his dad says that he can mow lawns for 12 hours at most (because it’s too hot over the summer), what is the fewest number of hours he’d have to work at the daycare? (2 points)
*remember that the lawn service hours are the “x” values.*

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

6 purchases

if you are asking how many of each then:

18 social media ads

6 newspaper ads

the results from a pre-test for students for the year 2000 and the year 2010 are illustrated in the box plot. what do these results tell us about how students performed on the 29 question pre-test for the two years?

if we compare only the lowest and highest scores between the two years, we might conclude that the students in 2010 did better than the students in 2010. this conclusion seems to follow since the lowest score of 8 in 2010 is greater in value than the lowest score of 6 in 2000. also, the highest score of 28 in 2010 is greater in value than the highest score of 27 in 2000.

but the box portion of the illustration gives us more detailed information. the middle bar in each box shows us that the median score of 20 in 2000 is greater in value than the median score of 17 in 2010. further, we note that the box and whiskers divide the illustration into four pieces. each of these four pieces represents the same portion of students. so, the upper half of the students in 2000 scored in the same score range as the upper one-fourth of the students in 2010, see the illustration at a score of 20.

by considering the upper one-fourth, upper half, and upper three-fourths instead of just the lowest and highest scores, we would conclude that the students as a whole did much better in 2000 than in 2010. we would conclude that as a whole the students in 2010 are less prepared than the students in 2000.

in this section, we discuss box-and-whisker plots and the five key values used in constructing a box-and-whisker plot. the key values are called a five-number summary, which consists of the minimum, first quartile, median, third quartile, and maximum.
