Simran charges a flat rate of

**$15**per call plus an hourly rate of

**$3.50**. Liem charges

**$10**per call plus an hourly rate of

**$4.25**. How long of a call would they charge the same amount?

So, we were suppose to graph this question on Excel. I would show you how but unfortunetly I don't have it. -_-" I use to but since my computer got upgraded.. It disappeared. Sorry guys, I'm a

**fail**-_-"

Well, thats practically all we did in class. We also got our

**Stash-its**back! Its about time... AHAHA. ^_^

We ended the class by going on www.mathplayground.com , and played Saving the Zogs. Tehehe :) Well that's all, bye guys !

Simran's rate = 15 + 3.5/hour

Liem's rate = 10 + 4.25/hour.

Let's say for a call of x hours, both charges comes out to be same. So we can write :

15 + 3.5*x = 10 + 4.25*x , Simplifyng :

15-10 = 4.25*x - 3.5*x

5 = 0.75*x

x = 5/0.75

x = 6.66 hours.
