thanks for the answer
Thank for sharing!
Thank you very much!
thanks, this one was pretty easy once I realized it's just revenue minus cost
yeah same, the (z-r) part had me for a sec tho lol
wait why is it (z-r) and not just z? the farmer still paid for all z pounds right
he paid for all of them but only sold (z-r) since r got damaged, so revenue is only on what he sold
ohh got it, cost is on z but the selling part is on the rest. thanks!
isn't E basically the same thing just factored?
What it tests
Your ability to manipulate linear and quadratic expressions, substitute unknowns, and solve equations under time pressure.
Common trap
Losing a sign when moving terms across the equals sign, or dividing both sides by a variable that could equal zero.
