Hello there! An example problem for this could be:
Emile is looking for a cell-phone plan. His two options are one that costs $40 up front, and costs $0.01 per text, represented by x. The second one is 15 dollars up front and costs $0.06 for each text message. Emile figures that for the first package he has to send 500 texts or more to make it less than the second one.
I need to know the distance.
speed= distance/ time
If you want to figure thier speed you need to divide the distance ( miles) by their time ( hours)
57+23 = 80
not rounded it's 80.14
Here you go!! It's always best to graph these questions, if you have graph paper near.
If not there are online graphing websites to use!! :))
