Question 838395: NOT GOOD AT MATH!!! The cost, T, in hundreds of dollars, of tuition at one community college is given by T=2+7/5C (belong to fraction), where c is the number of credits for which a student registers. Graph the equation and use the graph to estimate the cost of tuition if a student registers for 11 credits.

You can put this solution on YOUR website!
+T+=+%287%2F5%29%2AC+%2B+2+
Since +T+ depends on what +C+ is, you
plot +T+ on the vertical axis and +C+
on the horizontal axis.
----------------------------
Here's the graph:
+graph%28+400%2C+400%2C+-2%2C+20%2C+-2%2C+20%2C+%287%2F5%29%2Ax+%2B+2+%29+
------------
If +C+=+11+
+T+=+%287%2F5%29%2A11+%2B+2+
+T+=+77%2F5+%2B+2+
+T+=+15.4+%2B+2+
+T+=+17.4+
The cost is +T+=+100%2A17.4+ = $1,740
