Need help !! i will mark you as brainliest ! You are selling candy bars. It cost $140 for a startup fee and $1.50 per candy bar. Your income is based on the fact that you are selling the candy bars for $4.00 each.

1. What is the profit from selling 40 candy bars? The profit is $

2. What is the profit selling 100 candy bars? The profit is $

3. In order to break even you must
sell candy bars.

4. The minimum number of candy bars you must sell in order to start making a positive profit is cardy bars .

​

1. What is the profit from selling 40 candy bars? The profit is 40

2. What is the profit selling 100 candy bars? The profit is -110

3. In order to break even you must

sell 56 candy bars.

4. The minimum number of candy bars you must sell in order to start making a positive profit is 55.6 candy bars .

Step-by-step explanation:

equation: 140+1.50x-4x

140: startup fee

x: (amount) of candy bars

140 + 1.50 × 40 -  4 × 40

= 40

plug in 40 for both x's that are in the original equation. solve it out, and you get 40.

140 + 1.50 × 100 - 4 × 100

= -110

same thing as the part above, but plugging in 100 instead.

now to make the profit and the money you earn even, you have to find what number for x, makes the equation equal to 0.

140 + 1.50x - 4x = 0

after doing that, you solve for x

140 + 1.50x - 4x = 0

subtract 140 from each sides

1.50x - 4x = -140

now subtract 1.50 from 4

-2.5x = -140

now divide -2.5 from both sides which gives the

x = 56

which means that to make it even, you need to sell 56 candy bars

same as above, you solve for x but make the equation equal to 1

140 + 1.50x - 4x = 1

after solving, you get 55.6 candy bars

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.
