I’m working on a Algebra exercise and need support.
Select one of the options below and create a linear equation to represent the monthly bill for each Plan A and Plan B, you will have two equations, one for each plan. Find the common number of minutes at which both Plan A and Plan B cost the same amount. This number of minutes is called the break-even point. Which plan costs more before the break-even point and which cost more after the break-even point.
Option 1: Plan A $39.99 for 200 min and $1.25 for each min after. Plan B $29.99 for 200 min and $1.50 for each min after.
Option 2: Plan A $25.75 plus $.75 per min. Plan B $20.99 plus $1.00 per min
Option 3: Plan A $39.99 plus $1.25 per min. Plan B $25.99 plus $1.75 per min
Option 4: Plan A $45.99 for 400 min and $.50 for each min after. Plan B $49.99 for 400 min and $.40 for each min after
A Microsoft Excel spreadsheet is required for this DQ.
