Are you supposed to estimate or get an exact answer? If you're estimating you can see if the number is close to any perfect squares. In this case 63 is very close to 64, and 48 is very close to 49. The answers can then be estimated to be approximately 8 and 7, respectively.
Answer:
0.5

Hope this helped :)
The easiest way is to make equations y=2400x+30000 and y=2000+36000
and then put that in the calculator and go to table and the point they intersect at is (15,66000)
t would be graph: B (0,4)
All the equivalent fractions.
I'm fairly certain that's correct but check again if you need to and please, correct me if I got something wrong.
