If soda requires w liters of water for 1 liter of syrup, there will be w*m liters of soda for for m liters of syrup.

Soda costs j dollars a liter so wm*j will be the selling cost of soda. Syrup costs k dollars, so it will cost m*k to produce soda.

gross profit: wmj-mj = m(jw-k)

jm(1/w + 1)
m(jw -k)
(j-k) m
jm(1+w) - km

This is quite confusing,. please help me find the best approach. Thanks


Should be C.

lets say we have 5liters of water for 1 liter of syrup. That means when we have 5 liters of syrup we have 25 liters of water.

now just same idea. w*m ---> m(jw-k).

Remember Profit= Revenue-Cost.

Answer is E!!

Water for m liters of Syrup = WM
So total soda is wm + m liters

Selling price (wm + m)j
Cost Price = mk

Profit = mj(w+1) - mk

for m litres of syrup water required is w*m litres. total litres of solution is m+ wm

Now this solution is sold for j$ /litre of the solution. So total overturn is j*(m+ wm) and total cost = m*k

Gross profit is jm(1+w)- mk

Given Soda has w:1 ratio of Water to Syrup

Soda is made using m litres of Syrup. THis means m*w litres of water. Therefore total Soda made in litres = w*m+m = m(1+w)

Selling price of soda per litre = j dollars
Selling price of m(1+w) litres of soda = j*m(1+w) dollars

Cost of syrup per litre = k dollars
Cost of m litres of syrup used = km dollars

Gross Profit = Selling price of Soda - Cost price of Syrup = jm(1+w) - km... (Ans E or 5)

A recipe for soda requires w litres of water for every litre of syrup. If soda is made according to this recipe using m litres of syrup, and sold for j dollars a litre, what will be the gross profit if syrup costs k dollars a litre and water costs nothing?

A. m(w+j-k)
B. jm[(1/w)+1]
C. m(jw-k)
D. (j-k)m
E. jm(1+w)-km

Since soda requires \(w\) liters of water for every liter of syrup, then \(m\) liters of syrup gives \(water+syrup=mw+m\) liters of soda.

Sales = \(j(mw+m)\) dollars.
Cost = \(km\) dollars.

Profit = \(j(mw+m)-km\).

Answer: E.

Since every litre of syrup requires w litres of water and there are m litres of syrup, we need mw litres of water, and together with the m litres of syrup, we can make mw + m litres of soda.

Since we are selling the soda for j dollars a litre, we can make j(mw + m) dollars. However, since the syrup costs k dollars a litre (water costs nothing), we have a cost of km dollars. Thus, the total profit from selling the soda is:

j(mw + m) - km = jm(w + 1) - km

Answer: E
