Ricardo is considering two monthly plans a dog-walking service offers. • Plan 1 charges $3 per walk plus $10 for grooming at the end of each month.
• Plan 2 charges $5 per walk and then offers free grooming at the end of each month.
Part A
Write an equation to model the number of walks, w, when the two plans cost the same amount.
Part B
How many walks will it take for the two plans to cost Ricardo the same amount?

Trish receives $450 on the first of each month. josh receives $450 on the last day of each month. both trish and josh will receive payments for next four years. at a discount rate of 9.5 percent, what is the difference in the present value of these two sets of payments?

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.
