So to find this out let's start by finding out what 1/5 is equal to in this problem.

To do that we will divide the total by 5.  2325.35/5 = 465.07  We now know that 1/5 equals 465.07

We know that he put 2/5 in his savings which means he put 3/5 into his checking (2/5 + 3/5 = 5/5 or the whole sum of money)

So if we know that 1/5 is equal to 465.07 and he put in 3/5 we need to multiply 465.07 by 3.

465.07 * 3 = $1395.21  This is how much was put in his checking account

On a certain route, an airline carries 5000 passengers per month, each paying $70. A market survey indicates that for each $1 in
Mkey [24]

Answer:

$85

Step-by-step explanation:

5000 x $70 = $350,000

4950 x $71 = $351,450

4900 x $72 = $352,800

etc.

Create an equation for the monthly revenue:

f(n) = (5000 - 50n) x (70 + n)

     = 350000 + 5000n - 3500n - 50n²

     = 350000 + 1500n - 50n²

where n is the amount the ticket price is increased from $70.

Differentiate, equal to zero and solve for n to find the value of n when the monthly revenue is at its maximum:

f'(n) = 1500 - 100n

1500 - 100n = 0

1500 = 100n

15 = n

Therefore, the maximum monthly revenue is when n = 15.

So the cost of the ticket will be 70 + n = 70 + 15 = 85
