Question

A local boys club sold 136 bags of mulch and made a total of $271. It sold two types of mulch: hardwood for $2.50 a bag and pine bark for $1.75 a bag. How many bags of each kind of mulch did it sell.

Answer 1

hardwood 44

pine 92

Explanation:

set up a system of equations and use substitution

h + p = 136

2.5h + 1.75p = 271.00

p = 136 - h plug this into the second equation and solve for h

h = 44

plug 44 back in to the first equation to get p

p = 92
