Write and solve a real-world problem that represents the following one-variable inequality.

40 + 0.01x ≤ 15 + 0.06x

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.
