A) Let b and r represent the cost of a bag of bark mulch and red mulch, respectively. (Always start with a "let" statement that defines your variables--usually based on what the question is asking: cost of each type.)
8b +6r = 44.50 . . . . Paul's first purchase
1b +8r = 25.50 . . . . .Paul's second purchase
b) There are many ways to solve a set of linear equations like this. I like a graphical calculator because it gives me the solution without having to think too much or do any arithmetic.
(b, r) = (3.50, 2.75)
Pine bark mulch costs $3.50 per bag.
Red mulch costs $2.75 per bag.
c) The project cost would have been
.. 14*$3.50 +10*$2.75 = $76.50
Paul would NOT have been able to make that purchase with funds available.
Simple she gets either 2 lollipops and 2 candy bars or get 4 lollipops and 1 candy bar.
2x+6=x+3 this is the answer
I think the equation is still the same as a non-right triangle. a=(w*l)/2
As long as it's a triangle, that would be the equation. This is because for finding the area for a square or rectangle (quadrilateral) is always a=w*l, that means that the equation for any triangle is always a=(w*l)/2. The division by 2 for the triangle's equation is there because a triangle is half of a quadrilateral. So you would have to divide the quadrilateral's equation by two. Hope I helped :)
Answer:
For instance, say you pay $8,000 for goods and sell them for $10,000. Your gross profit is $2,000. Divide this figure by the total revenue to get your gross profit margin: 0.2. Multiply this figure by 100 to get your gross profit margin percentage: 20 percent.
