Respuesta :

after 401 flyers Company A has a better deal.

First it's important to note that, at 400 flyers they are equal.
39.99+0.5x=0.6x
-0.5x. -0.5x
39.99=0.1x
multiply both sides by ten
399.9=x
there can't be .9 flyers so round up to four hundred.
so, go one up (the easiest way to find which is larger after the part where they are equal) sorry this probably makes no sense... but
this is algebra. if this is to complex, try graph it. just use the cost for flyers as the x axis and the design as the initial cost so the y intercept.
but if u want to do it as an equation, just plug in 401 to both equations.
here are the equations I used from above:
company A- 39.99+0.5x
company B- 0.6x
I used a calculator for this part because it's easier. the second one had more. it was 240.6 for 401 flyers for the second one, and 240.49 for 401 flyers for the first. So... company A is actually cheaper at 401 and the more you purchase the better the deal will be compared to B.
I'm sorry if I explained that badly. just use a graph. lol
