Answer:
after 272 mins
Step-by-step explanation:
make it into two linear equations y=.19x and y=29.95+.08x
First factor out a variable: x(x^2-2x-24)
now solve the quadratic: x(x-6)(x+4)
When you set these expressions equal to zero, you get 0, 6, and -4 as your answers.
I believe it should be 4. Because a trend line should be a line that shows the trend haha so it should be equal. Not sure if that makes sense sorry if I didnt explain it well.
