Complete question :
Jordan is mixing water and flour to make tortillas. The number of cups of water, w, needed for f cups of flour is described by the equation w = 0.75f
How many cups of water are needed to mix with 4 cups of flour?
Answer:
3
Step-by-step explanation:
Given the relation :
w = 0.75f
Where w = number of cups of water ; f = cups of flour
Cups of water needed to mix 4 cups of flour :
f = 4
w = 0.75(4)
w = 3
Hence, 3 cups of water is required to mix 4 cups of flour.
We can write that as a function:
where is the number of price reductions. We can see that it is a quadratic function which has the biggest value at P = (p, q). It means that p is the number of reductions which results in the biggest profit.
It means that it's the best to make 2 price reductions for the company. The tickets should be sold for $200 - 2 * $20 = $160. It results in 2 * 50 more tickets sold which is 300 + 100 = 400.
Answer:
Ticket price: $160
Number of tickets: 400
