Your long distance telephone provider offers to plans plan a has a monthly fee of $15 and $0.25 per minute. plan b has a monthly fee of $20 and $0.05 per minute. right and solve an equation to find the number of minutes that you must talk to have the same cost for each of the plans

The equation for plane a and plane b is
15+0.25x = 20+0.05x find the x and plug them in the equation i hope that helps

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
