Question

a seed company sells two grades of grass seed. And hundred pound bag of a mixture of rye and Bluegrass sells for $255, and a hundred pound bag of Bluegrass sales for $348. How many bags of each are sold in the week when the receipts for 18 bags are $5334?​

Answer 1

8 bags of rye & bluegrass mix

10 bags of bluegrass

Explanation:

RB = bags of rye & bluegrass mix

B = bags of bluegrass

348B + 255RB = 5334

RB+B = 18 then RB = 18-B

substitute for RB

348B + 255(18-B) = 5334

348B + 4590 - 255B = 5334

reduce

93B = 744

B = 8

RB = 10
