A tablet data provider offers different plans for data usage. The plan Raul chose has a monthly fee of $29.99 per month for 5 GB
if data with an additional cost of $10 for each gigabyte over 5. a. Write an expression for Raul’s monthly data costs.
b. Raul learns that his data provider is iffy unlimited data plan for $59.99 per month. Find the minimum number if gigabytes Raul could use per month to make the unlimited plan cheaper than his current plan. Explain your solution process.
We must know that the are of the triangle is given by definition by A = (1/2) * (b) * (h) where b = base h = height Substituting the values A = (1/2) * (x) * (1 + 6x) A = (1/2) * (x + 6x ^ 2) Since the area is 13 then (1/2) * (x + 6x ^ 2) = 13 Clearing x we have 6x ^ 2 + x = 26 6x ^ 2 + x-26 = 0 (x-2) * (x + 13/6) = 0 As we look for the base of a triangle then x> 0 x = 2 answer the base is x = 2 6x ^ 2 + x = 26
