Answer:
she bought 8 coach, 2 first-class
Step-by-step explanation:
let x = number of coach tickets
equation I used: 320x + 960(10 - x) = 4480
320x + 9600 - 960x = 4480
-640x = -5120
x = 8
In a survey with 60 people, each people would get 1/60th of the chart which has 360 degrees, so everyone would get 360/60=6 degrees
and 13 people would get 13*6=78 degrees!
The solution to the problem is as follows:
We have 2+.8(2) + .8(.8(2)) + .8(.8(.8(2))) + ... =
2( .8^0 + .8^1 + .8^2 + .8^3 + ... ) =
2(.8^n -1) / (.8-1) . As n-->infinity, .8^n-->0 giving us
<span>2(-1)/(-.2) = 2(5) = 10 meters.

(b) The monthly savings of Juan is $200.
(a) The monthly saving of Juan is $900.
(c) The monthly saving of Juan is $3,600.
As we know that
Savings = Income - expenses
So based on the above formula, the monthly savings in each case is as follows:
(b)
Monthly saving is
= $3,600 - $3,400
= $200
(a)
Monthly saving is
= $3,600 - $2,500
= $900
(c)
Monthly saving is
= $3,600 - $0
= $3,600
Here we assume the x be zero.
Therefore we can conclude that
(b) The monthly savings of Juan is $200.
(a) The monthly saving of Juan is $900.
(c) The monthly saving of Juan is $3,600.
