The question is:
A recipe for a batch of 3 dozen chocolate chip cookies calls for 3 cups
of flour 1 cup of suger and 2 cups of chocolate chips how much of each
ingredient should be used to make 2 dozen cookies?
find ratio
for 3 dozen batches, you need 3 cups of flour
so dozen of batches=number of cups of flour
then 3 dozen batches is 1 cup of sugar
so every dozen batches is 1/3 cup sugar
then 3 dozen batches is 2 cups choc chips
so every dozen is 2/3 cups choc chips
for 2 batches
that is 2 cup of flour
2/3 cup of sugar
and 4/3 cup chocolate chips
The problem is asking how much each person will need to pay. Simplifying the problem into an equation with variables (an algorithm) will greatly help you solve it:
S = Sales Tax = $ 7.18 per any purchase
A = Admission Ticket = $ 22.50 entry price for one person (no tax applied)
F = Food = $ 35.50 purchases for two people
We know the cost for one person was: (22.50) + [(35.50/2) + 7.18] =
$ 47.43 per person. Now we can check each method and see which one is the correct algorithm:
Method A)
[2A + (F + 2S)] / 2 = [ (2)(22.50) + [35.50 + (2)(7.18)] ]/ 2 = $47.43
Method A is the correct answer
Method B)
[(2A + (1/2)F + 2S) /2 = [(2)(22.50) + 35.50(1/2) + (2)7.18] / 2 = $38.55
Wrong answer. This method is incorrect because the tax for both tickets bought are not being used in the equation.
Method C)
[(A + F) / 2 ]+ S = [(22.50 + 35.50) / 2 ] + 7.18 = $35.93
Wrong answer. Incorrect Method. The food cost is being reduced to the cost of one person but admission price is set for two people.
