Question

Tracy has a cell phone plan that provides 250 free minutes each month for a flat rate of $29.

Answer 1

250 minutes with the flat rate of $29.

`x\leq 250`

x would be the number of minutes called.

`x-250`

Tracy would be charged by $0.35 per minute.

`f(x)=29\\ 0\leq x\leq 250`

`f(x)=0.35(x-250)+29,\\250\leq x\leq ∞`
