Answer:
$1151.4
Step-by-step explanation:
let americans spend $a in 2014
(1+4.8%)a=1180
104.8%a=1180
a=1151.4 (rounded off to the nearest tenths)
Move the x over to the other side
2y=10-5x
Divide both sides by 2 to get the y alone
y=-5/2x+5
Find m from the equation of a line (y=mx+b)
m=-5/2
Slope=-5/2
Given the cost of movie was increased by 15%
so desired result will be 8+8(15/100)
That gives you designed result of the ticket as 8+1.2=9.2
