Question

This is probably easy, but I am confused....help

Answer 1

as a math kid i shall try to help LOL

Answer 2

At the nuthouse, a pound of peanuts cost $3 per lb and cashews cost $6 per lb. If you want a mixture pf peanuts and cashews that weighs 3 lbs and costs $5.25, how many cashews would you need to purchase ?

I set it up like this...
p + c = 3
3p + 6c = 5.25

I am getting 4.25 = c and that can't be right....unless it is ounces. Am I doing something wrong ?

Answer 3

aghh let me get pen and paper

Answer 4

lol....ok

Answer 5

is the 4.25 in ounces or did I set it up wrong ?

Answer 6

Answer 7

sorry im actually just the history kid xD

Answer 8

lol..I understand....I like History also

Answer 9

hmm...lol argh I need a paper and pen also lol...in my head is NOT working...

Answer 10

mine is not either...as you can see

Answer 11

ohhh wait....I see a mistake in my work.....in my work I put 3c + 6p = 5.25 and it should be 3p + 6c......let me do it again....

Answer 12

p + c = 3 -->p = 3 - c
3p + 6c = 5.25

3(3 - c) + c = 5.25
9 - 3c + c = 5.25
-2c = 5.25 - 9
-2c = -3.75
c = 1.87 rounds to 1.9

I think I got it now

Answer 13

I feel stupid

Answer 14

Not quite...you forgot the "6c" in the first part of your solving...

Answer 15

I really feel stupid now....I can do it now.....thanks for looking at this

Answer 16

p + c = 3 -> p = -c + 3
3p + 6c = 5.25

3(-c + 3) + 6c = 5.25

-3c + 9 + 6c = 5.25

3c + 9 = 5.25

3c = -3.75

c = a negative number?

Lol I'm so confused...but good luck!

Answer 17

it is negative.....is it set up wrong ?
