Answer provided by our tutors
let the 100-pound bag of mixture of rye and Kentucky bluegrass = x
let the 100- pound bag of bluegrass = y
total bags 19
x+y=19 -----> x= 19-y
A 100-pound bag of

$347 each are
sold 10 a week when the receipts for
19 bags are $5,369
245x+347y=5369
245(19-y)+347y=5369
4655-245y+347y= 5369

y=7
x=19-7 =12
