A local boys club sold 156 bags of mulch and made a total of $596. It sold two types of mulch: hardwood for $4.00 a bag and pine bark for $3.75 a bag. How many bags of each kind of mulch did it sell?

44 bags of hardwood, 112 bags of pine bark mulch.

we have two equations. I’ll call hardwood h, and pine bark p.

The number of bags: h + p = 156
The cost of the bags: 4h + 3.75p = 596

Start by solving the first equation for h in terms of p
h = 156 - p

Then substitute that in the other equation for h, and solve for a numerical value of p

4(156-p) + 3.75p = 596
624 -4p + 3.75p = 596
28 = 0.25p
p = 112

Now plug that in to the first equation to get the numerical value of h
h + p = 156
h + 112 = 156
h = 44

Check the math:
4(44) + 3.75(112)
176 + 420 = 596

Ifound this on google “a skewed (non-symmetric) distribution is a distribution in which there is no such mirror-imaging. a "skewed right" distribution is one in which the tail is on the right side. a "skewed left" distribution is one in which the tail is on the left side. the above histogram is for a distribution that is skewed right.” i hope this you for what your looking for
