Answer:

37.5

Step-by-step explanation:

so x% of 40 is 15

the equation for that is

x/100 * 40 = 15

40x/100 = 15

multiply 100 on both sides

40x = 1500

divide 40 on both sides

37.5

37.5% of 40 is 15

Answer:

37.5

Step-by-step explanation:

Just do 15 out of 40 and divide 15 by 40 for the answer.

40/15

add a zero to the 15

40 goes into 150 3 times (40*3= 120)

150-120=30

40 doesn't go into 30 so you add another 0 which makes it 300

40 goes into 300 7 times

300-280= 20

40 doesn't go into 20 so add another zero (200)

40 goes into 200 5 times (40*5=200)

37.5

What is TR (915)- TR (895)=
tangare [24]

The result is TR (20).

To determine the result of TR (915) - TR (895), the following logical-mathematical reasoning must be made:

We find a constant that is repeated in both values, which is TR.

In turn, both values have a different quantity, which multiplies that constant.

Therefore, you must perform this multiplication and then subtract the results, to obtain the final result.

  • TR (915) - TR (895) = X
  • 915TR - 895TR = X
  • 20TR = X

 

Therefore, the result is TR (20).

An airline finds that if it prices a cross-country ticket at $200, it will sell 300 tickets per day. It estimates that each $20
olya-2409 [2.1K]

We can write that as a function:

f(n)=(200 -20n) * (300 + 50n)\\f(n)=60000+10000n-6000n-1000n^2\\f(n)=-1000n^2+4000n+60000\\

where n 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.

p=\frac{-b}{2a}=\frac{-4000}{-2000}=2

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
