Step-by-step explanation:
I got 15xy+7y+5x
First, create a scale that includes all the numbers- that being, you can plot both the minimum and maximum values on it.
Next, draw a line of a set height (I tend to use 2 squares in my work) where the median is. Next, draw similar lines, at the same height, for the rest of the values- both quartiles and the maximum values. You can obviously do this in whatever order you like, but that's how I do it.
Next, join up the tops and bottoms of the quartiles, with the median in the middle, and connect the middles of the quartiles to their corresponding minimum or maximum values.
Voila, my friend. You have a box plot.
1500 points= 100%
x =68%
(68)(1500)/100= 1020
He must have 68%(1020points) of the 1500 points
He has 953 points
1020-953= 67
He must earn 67 more points by the end of the term
