Question 1124077
This is two straight line equations, and the
Intersection is the point where the costs of
A and B are the same
Let {{{ C }}} = cost and plot it on the vertical axis
Let {{{ p }}} = the number of pages plotted on horizontal axis
———————-
Company A:
(1) {{{ C = .6p + 3 }}}
Company B:
(2) {{{ C = .75p }}}
———————————
Make the costs the same:
{{{ .75p = .6p + 3 }}}
{{{ .15p = 3 }}}
{{{ p = 20 }}}
A will cost less that B if there is 1 less page. Fractions
Of a page are probably not allowed, so 19 pages
Will make A cost less than B
Here’s the plots:
