audra and tom r working in the school kitchen on soup day. their job is to make 8 liters of chicken noodle soup in a large pot. they have only small cans (0.284 liters) of soup. they will add 1 can of water for each can of soup.
a.) how many small cans of soup are needed to make 8 liters?
b.) how many students could be served if each student received 0.190 liters of the soup?
c.)small cans of soup each cost $0.97. the school sells soup at $1.00 a bowl. what is the profit on the 8 liters of soup?
d.)what assumpitions do u need to make to answer part c.)?
e.)what other costs might be involved in the sale of soup?
okkkk that took me awhile… this is only grade 7 math, but i can’t figure it out. i’m not asking u to answer it, but u can if u want, maybe if u get it (i don’t) maybe u could just tell be how to find teh answer…
thanks 
btw this is a canadian textbook so all units of measurements r canadian, same goes for the prices, they r all in canadian dollars. if that matters…

audra and tom r working in the school kitchen on soup day. their job is to make 8 liters of chicken noodle soup in a large pot. they have only small cans (0.284 liters) of soup. they will add 1 can of water for each can of soup.
a.) how many small cans of soup are needed to make 8 liters?
Each can of soup makes .568 liters. You need 8 liters
8/.568 = 14.08
You need 14 cans of soup. It will be just a bit less than 8 liters or you can use 15 cans and have 8.5 liters of soup.
b.) how many students could be served if each student received 0.190 liters of the soup?
8/.190 = 42.1
42 students
c.)small cans of soup each cost $0.97. the school sells soup at $1.00 a bowl. what is the profit on the 8 liters of soup?
42(1.00) – 14(.97) = 42 – 13.58 = 28.42
Profit is $28.42
d.)what assumptions do u need to make to answer part c.)?
That all the soup will be sold.
e.)what other costs might be involved in the sale of soup?
cost of utilities (gas or electricity for heating the soup and water to add to soup), cost of disposable bowls and spoons or cost to wash bowls and spoons, cost to pay employees who make and sell soup and clean pots, bowls, spoons.
A.) I took 0.284 x 2 (the added water) = 0.568
Total soup of 8 liters divided by 0.568 total liquid = 14 (.08) cans of soup to make 8 liters of reconstituted soup.
B.) 8 liters soup divided by 0.190 = 42 (.105) students
C.) 14 cans of soup x $0.97 = $13.58 cans of soup used to make 8 liters. Sell 42 bowls of soup at $1.00 each = $42.00
$42.00 in soup sales minus $13.58 in soup can cost = $28.42 profit.
D.) You have to assume what your bowl size is. 0.25 liters? 0.5 liters? etc.
E.) Energy costs to heat the soup.
Water cost to make soup.
Energy & water costs to clean all dishes associated with making of soup & cleaning bowls that soup has been eaten out of.
Was all of the soup sold that day? If not, can it be sold next day? Can it be added as an ingredient in a new food later that week?
I told you how I did it so you can check the math. I did it in a hurry so figures could be wrong. You MUSt double check B4 submitting answer on your homework.
