A cell phone company offers a basic monthly plan that charges $20 for the first 60 minutes and $0.05 per additional minute. If you budgeted $60 to spend on your cell phone bill for the month, how many minutes can you use?

Question

sleepyjess · Answer

20+.05x=60
Solve for x

sleepyjess · Answer

Whatever you get for x, add 60 minutes to that

anonymous · Answer

The first thing i did was remove the 20$ from my budget. So i have 60 minutes and 40$ left.
Then I get .05x = 40
Solve for x then add 60 minutes from the begging

Omg thank you so much. Can you help me on my other math problems ?

sleepyjess · Answer

Sure!

anonymous · Answer

Point P (a, b), where neither a or b is equal to 0, is subject to the following operations, one after the other in any order:
reflection about the x-axis, reflection about the y-axis, reflection about the origin.
What will be the final position of point P?

sleepyjess · Answer

Since point P can be at any point except where a coordinate is 0, let's us 3, 3 to make this easier.
