Question

Devon wants 50 pounds of

tea that he can sell for $5.14/lb.
If he has tea that costs $7.80 per
pound and tea that costs
$4.30/lb, how much of each
should he use

Answer 1

12 lbs of $7.80

38 Lbs of $4.30

Explanation:

50(5.14)=7.8(x)+4.3(50-x)

257=7.8x+215-4.3x

42=3.5x

12=x, this is how many pounds of $7.80 you need, then subtract 12 from 50 to see how many pounds of $4.30 you need and check your answer
