Gertrude is deciding which cell phone plan is the best deal for her to buy. Super Cell charges a monthly fee of $10 and also charges $0.15 per call. She makes a note that the equation is M = 0.15C + 10, where M is the monthly charge, in dollars, and C is the number of calls placed. Global Cellular has a plan with no monthly fee but charges $0.25 per call. She makes a note that the equation is M = 0.25C, where M is the monthly charge, in dollars, and C is the number of calls placed. Both companies offer unlimited text messages.a. Make a table for both companies showing the cost of service, M, for making from 0 to 200 calls per month. Use multiples of 20.b. Construct a graph for the two equations on the same graph. Use the number of calls, C, as the independent variable and the monthly charge, in dollars, M, as the dependent variable.c. Which cell phone plan is the best deal for Gertrude? Defend your answer with specific examples.

Helen holds 1,000 shares of Fizbo Inc. stock that she purchased 11 months ago. The stock has done very well and has appreciated $20/share since Helen bought the stock. When sold, the stock will be taxed at capital gains rates (the long-term rate is 15 percent and the short-term rate is the taxpayer’s marginal tax rate). Ignore the time value of money. If Helen’s marginal tax rate is 35 percent, how much would she save by holding the stock an additional month before selling?

Which inequality represents the solution set that shows the number of passengers, LaTeX: pp, that can still load the plane? p < 78 p ≤ 68Correct! p ≤ 78 p ≥ 78Sara is serving wings and burgers at her party. Wings cost $6.00 per serving and burgers are $3.00 each. Sara knows that at least 4 of her friends want wings. Sara must spend less than $45.00. Sara graphs a system of inequalities to determine how many servings of each kind of food she could serve to stay within her budget.According to the dark blue area on the graph, what is the maximum number of burgers that Sara could serve with 6 servings of wings? the answer is 2 the other ones is incorrect which is 3 4 5An Uber driver charges $0.50 per mile and an initial fee of $3. A Lift driver charges $0.60 per mile and an initial fee of $2.
