Compare the full-year plan cost
See this course’s project requirements
A compact fictional access plan: a needs card, three-offer annual cost table, changed-input choice, availability gate and backup questions.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- A needs card with data quantity, upload-rate threshold, device/use requirements and unknown coverage marked separately.
- Three complete twelve-month comparisons including promotion periods, equipment, setup and stated excess-data charges; one changed-use recalculation.
- A revised decision after the supplied availability replies, an unsent provider question and one provisional backup route.
Review and revise
Use these criteria to check your work and choose what to improve.
- GB/MB quantity and Mbps rate are never treated as the same unit; the supplied task constraints are retained.
- Every month and one-time cost is counted once, and partial excess-data blocks follow the supplied fictional rule.
- The decision changes when the relevant need or availability changes; excluded plans have a named reason.
- Real availability, compatibility, performance and assistance are kept pending until verified; no purchase, free service or subsidy eligibility is claimed.

The idea in everyday life
Use Ellis’s original 60 GB/month. The invented offers apply identically in each of twelve planning months. Prices are fictional USD. These cards include every charge for this case: no tax, discount, bundle, early-ending fee or additional mandatory cost applies. A charges $10 for each started 10 GB block above 50 GB in a month; no unused data carries forward. All three support compatible laptop access and permit calls; actual practice-location availability is still unknown.
Count every promotion month, ordinary-price month, equipment charge and one-time fee. Then apply the plan’s stated data rule to the same monthly use.
Compare the full-year plan cost — worked practice
Count every promotion month, ordinary-price month, equipment charge and one-time fee. Then apply the plan’s stated data rule to the same monthly use.
Draw columns for base annual USD, extra-data annual USD, combined annual USD, upload screen and pending access. A started block means round the positive excess up to a whole block: 1 GB above the limit still incurs one block. Do not purchase a plan or look up your address.

Copy as plain text
1. Count every base-price month
Calculate each annual base including the stated recurring equipment and one-time setup.
A=6×25+6×45+12×5+20; B=12×45; C=3×35+9×55+30You should see: A=$500; B=$540; C=$630. Every plan covers twelve months.
A low first price does not describe the later months.
2. Apply A’s data-block rule
Use 60 GB in every month; find excess above A’s 50 GB allowance, started blocks and yearly charge.
You should see: 10 GB/month excess is one 10 GB block/month. Extra charge $10/month, or $120/year. A’s combined cost is $620/year.
The block fee repeats each month under these supplied terms.
3. Screen the supplied rate
Compare each upload rate to the at-least-3-Mbps requirement.
You should see: A 5 Mbps and B 10 Mbps pass the stated rate screen. C 2 Mbps fails, even though its data quantity is unlimited.
Unlimited data quantity does not imply a required transfer rate.
4. Choose provisionally
Compare fitting offers and keep location availability pending.
You should see: B: $540/year, compared with A: $620/year. B is provisionally cheaper by $80/year; no purchase or service-availability pass is established.
A low cost cannot replace missing access evidence.
What to finish
A three-offer twelve-month cost table with a rate screen and a provisional choice before availability is confirmed.
Watch for this
Multiplying the introductory price by twelve, ignoring equipment or treating a partial started excess-data block as free.
How can I tell I understand it?
Recalculate a changed monthly-use case and explain why the preferred eligible offer can change.
