Hi everyone!
This is my first post here at freemathhelp.
So here is the problem:
A grocer is making a snack mix containing Sunflower Seeds (costing $1 per pound) and Raisins (costing $2.70 per pound. In order to obtain 10 pounds of snack mix costing $1.50 per pound, how much of each ingredient should the grocer use?
My work so far:x = amt. of seeds in lbs
y = amt. of raisins in lbs.
x + y = 10
1.00x + 2.70y = 1.50
y = 10 - x
1.00x + 2.70(10 - x) = 1.50
1.00x + 27 - 2.70x = 1.50
-1.7x = -25.5
x = 15
15lb of seed in a 10lb mix? Lol i'm lost.
