you can write an equation to solve this

anonymous · Answer

i need the answer @mathessentials

anonymous · Answer

5*s + g = $720

anonymous · Answer

whats the answer?
@mathessentials

anonymous · Answer

set into s, and g the price of the vegetables :)

write equation here

anonymous · Answer

5*s + g = $720

anonymous · Answer

i still dotn understand what is the answer? @mathessentials

anonymous · Answer

we can make two equations

is that acceptable?

anonymous · Answer

wait

5*$6*x + $10*x = $720

how does this work?

well, every sougaru costs $6, so a sougaro
is $6*x in the eq.
(similarily, every goldencactus cost $10, so $10*x from those.)

also,i say that the sougaro ($6*x from total income) is 5 times as often
OK so that means that whenever there is one golden($10*1) there is
($6*5) or 5 sougarus, right ?? I sell one golden, I get 5 sougarous at the
same time to have the total balance as in the problem.

anonymous · Answer

5*$6*x + $10*x = $720

i can pull the unknown x out:
x(5*$6+$10) = $720
x($30+$10) = $720
x($40) = $720      divide by $40
x = $720/$40 = 18

anonymous · Answer

so she sold 18 golden cactus,
and if that is so, then she also sold 5*golden with it ; )
so that would be 18*5 = 90 sougarous.

anonymous · Answer

we can check if thats correct.

90 sougarous for $6/pc
+ 18 golden cactus for $10/pc
-------------------------
??

$540
$180
-----
$720, yep that's it!

the way I solved it was by getting ONE UKNOWN for both vegetables.
by doing that, I was able to determine that one unknown.

then, I can calculate every separate vegetable.

anonymous · Answer

what I did was basically to say that, there are just a few possible
sellings, if you know one is sold 5 times the other:|dw:1382622309118:dw|

anonymous · Answer

you can change the total revenue, and
the amounts will change automatically from 5:1 to 10:2, 15:3
and the price will also be adjusted, since I put $ next to each veg :)
