answer is 2

i didn't read the per pound part so you have to find 4.20 x 5

so it'd be

3x+6y=5*4.20
x+y=5

Seems weird to me

hero · Answer

The chocolate already costs $6 per pound. Why would you buy two of them?

anonymous · Answer

because you are buying 5 pounds of mixture.. so you are essentially buying 4.20 * 5 of the mixture

hero · Answer

That's not a good enough explanation

anonymous · Answer

which is 21 dollars... i was getting negative answers the first time lol since i did if it all cost 4.20 lol

anonymous · Answer

3(3)+2(6)=21? is that good enough explanation?
