On a particular flight, the airline's income was $95,280 for a jumbo jet carrying 290 passengers. If a first-class ticket costs
SIZIF [17.4K]

Answer:

30 first-class tickets were sold and 260 coach tickets were sold.

Step-by-step explanation:

Let a first-class ticket be represented by f and let a coach ticket be represented by c.

On a particular flight, a jumbo jet was carrying 290 passengers. So, the sum of the first-class tickets and coach tickets must sum to 290:

f+c=290

The total income was $95,280. Therefore:

680f+288c=95280

We can now solve the system of equations. First, we can simplify the second equation by dividing everything by 8:

85f+36c=11910

From the first equation, we can subtract f from both sides:

c=290-f

Substitute:

85f+36(290-f)=11910

Distribute:

85f+10440-36f=11910

Simplify:

49f=1470

So:

f=30

From the previous equation:

c=290-f

Substitute:

c=290-30=260

30 first-class tickets were sold and 260 coach tickets were sold.

If
vitfil [10]

Answer:

x =  \frac{1}{e}

Step-by-step explanation:

f(x) = {(lnx)}^{2}

f1st(x) =  \frac{2 lnx }{x}  = 0

x   <  1 \:  \:  f1 < 0 \:  \: de creasing

f2nd(x) =  \frac{2 - 2 lnx}{ {x}^{2} }  = 0

x  <  e \:  \: f2 > 0 \:  \: concave \: up

So x<1 is the condition which contains x=1/e

mezya [45]

Answer:

P = 17t + 7

Step-by-step explanation:

P = 2L + 2w

L = 1.5t + 5

w = 7t - 1.5

P = 2*(1.5t  + 5) + 2*(7t - 1.5)

P = 3t + 10 + 14t - 3

P = 17t + 7
