Answer:
The total number of hardwood mulch is 48 and pine bark mulch is 128 and this can be determine by forming the linear equation in two variables.
Given :
A local boys club sold 176 bags of mulch and made a total of $520.
Sold two types of mulch : hardwood for $3.50 a bag and pine bark for $2.75 a bag.
Let the number of hardwood mulch be x and the number of pine bark mulch be y then the total number of mulch will be:
--- (1)
And the total amount is given by the equation:
---- (2)
Substitute the value of y in equation (2).
y = 128
Now, put the value of y in equation (1).
x = 176 - 128
x = 48
So, the total number of hardwood mulch is 48 and pine bark mulch is 128
