Final answer:
To create the expression representing the monthly bill for x minutes on the EZ Pay Plan, we combine the flat monthly charge with the cost for extra minutes used. The expression would be Monthly Bill = A + Bx, acknowledging A as the fixed monthly charge and B as the per-minute charge for minutes exceeding the plan.
Step-by-step explanation:
To represent the monthly bill for x minutes on the EZ Pay Plan, we need to know the specifics of the plan, such as any fixed monthly charge and the rate per minute once the allowed minutes are exceeded. Let's assume the EZ Pay Plan includes a flat charge and a per-minute rate. If the plan costs $A for the allowed minutes each month and you pay $B for each additional minute over the allowance, and you've used an extra x minutes, the expression for the monthly bill would be:
Monthly Bill = A + Bx
If a fixed rate or initial allowance is not part of your given information, you would need to amend the expression to fit the actual structure of the EZ Pay Plan.
