To compare the plans, we need to calculate the total cost for each plan based on Tyrone's usage of 800 minutes and 1000 text messages.
Plan A:
Cost = $95 (unlimited talk and text)
Plan B:
Cost = (Cost per minute × number of minutes) + (Cost per text × number of texts)
Cost = ($0.10/min × 800 min) + ($0.05/text × 1000 texts)
Cost = $80 + $50 = $130
Plan C:
Cost = Monthly fee + (Cost per minute × number of minutes) + (Cost per text × number of texts)
Cost = $20 + ($0.05/min × 800 min) + ($0.05/text × 1000 texts)
Cost = $20 + $40 + $50 = $110
Plan D:
Cost = Monthly fee + (Cost per minute × number of minutes)
Cost = $45 + ($0.10/min × 800 min) + (Cost of text messages = free)
Cost = $45 + $80 = $125
Now, let's summarize the total costs:
- Plan A: $95
- Plan B: $130
- Plan C: $110
- Plan D: $125
Now, let's put the plans in order from least expensive to most expensive:
- Plan A: $95
- Plan C: $110
- Plan D: $125
- Plan B: $130
So the final order is:
- Plan A
- Plan C
- Plan D
- Plan B
