Ok so here we go!
a steam and leaf plot is very simple to figure out
for example if a number was 6|4 it would equal 64
so for your first question range equals the biggest number subtracted by the smallest number so in your case it would be 28-55
which equals 27
Let's use the point-slope formula here:
y - 5 = -2(x - 3). That's it. You could, of course, rewrite this in slope-intercept form, as follows:
y = 5 - 2x + 6, or y = -2x + 11, in slope-intercept form.
X = original price
(7/5)x = 24000
x = (5/7)24000
x = 17143
the original price was $17,143
