1. The problem statement, all variables and given/known data
N * 45 min = N * 12$Is it correct? Zulfi. 5. Dec 2, 2017 ### Ray Vickson Don't ask---just solve it and check whether your solution satisfies the conditions of the problem. When you continually ask "is it correct" half-way through a solution (as you do over and over again in many of your threads) you are not developing the necessary confidence in your own abilities. What would you do on an exam, where you cannot ask anyone? 6. Dec 2, 2017 ### Mark44 ### Staff: Mentor No. 1) As an equation, 45 minutes does NOT equal$12. The units don't match at all.
2) Your second equation is wrong as well. You are omitting important information in this problem.

Let N = the number of classes Randilf was in this month.

How many minutes was Randilf in class this month?
How many dollars did Randilf spend for the classes this month?
Are these two numbers equal?
If not, which one is larger, and by how much?
