Emelia is booking a flight to San Francisco. The airline charges 5270 for the ticket and 16% for taxes and fees. How much will Emelia pay for her flight?
(show your work)

Answers

ANSWER:
$6113.20


EXPLANATION:
There is two ways to make an expression to solve this which is
y = 1.16x
or
y = x + 0.16x

Here is the explanation for the first expression, it is more thorough:

The airline makes her pay x amount in dollars for the ticket alone. Then, the airline charges an additional 16% of that x amount. Just a policy they’ve required.
Therefore:
y = x + 0.16x

• x is the ticket price
• 0.16x is 16% of that ticket price

Plug x with the initial charge amount:
y = 5270 + 0.16(5270)
y = 6113.20



10% of 5270 = $527
5% of 5270 = $263.50
1% of 5270 = $52.70
6% of 5270= $316.20
16% of 5270 = $843.20

$843.20 + $5270 = $6113.20

two vertical poles of heights 12 inches and 22 inches are separated by a horizontal distance of 24 inches. what will be the distance between the tops of these poles?

Answers

Answer: 26 in.

Step-by-step explanation:

Given

Heights of Poles are [tex]12\ in., 22\ in.[/tex]

distance between them is [tex]x=24\ in.[/tex]

the difference in heights of the pole is [tex]y=22-12=10\ in.[/tex]

From the figure, using Pythagoras theorem, distance L is given by  

[tex]\Rightarrow L^2=y^2+x^2\\\Rightarrow L^2=10^2+24^2\\\Rightarrow L^2=100+576=676\\\Rightarrow L=\sqrt{676}=26\ in.[/tex]

The distance between tops is 26 in.
