Hey guys, I need help with this word problem. I don't just want the answer. I would like the steps please!
ASHA 777 [7]
So, you take the equation for y given, y=0.28x+5.92. Then you substitute the values for x in, like so: 
y=0.28(2)+5.92=6.42
y=0.28(5)+5.92=7.17
y=0.28(8)+5.92=7.92
So There's your table. Next:
7.88=0.28x+5.92
x=7, so the year when admission was approximately $7.88 is year 7. 
Next, 
10.04=0.28x+5.92
x=<span>14.7142857143, which rounds to year 15. 
I hope this helps!</span>
