Answer:
x=8
Step-by-step explanation:
5x+10+130=180
5x+140=180
5x=40
x=8
From x=1 to x=5
x=1 is starting time
x=time
y=mx+b
m=slope
b=yintercept
slope=(y2-y1)/(x2-x1)
for points (x1,y1) and (x2,y2)
(1,52000) and (5,116000)
slope=(116000-52000)/(5-1)=64000/4=16000
y=16000x+b
find b
(1,52000)
52000=16000(1)+b
52000=16000+b
minus 16000 from both sides
36000=b
the equation is
y=16000x+36000
at 12 years, x=12
y=16000(x)+36000
y=16000(12)+36000
y=192000+36000
y=228000
sales at year 12 is $228,000
Answer: 7 months
