are u getting a new phone... or is this homework...? ;D jks, sry anytime plan = 39.99 / month basic plan = 22.99/month + 0.08x for what value of x will anytime plan = basic plan? get that value, add 300, as "on all calls AFTER the first 300 minutes" there's your final answer so set the equation up something like: anytime plan = basic plan 39.99 = 22.99 + 0.08x u rite to solve from here @taisadenice ?
