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:
hardwood 44
pine 92
Step-by-step 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
