Mrs Okafor asks: how much?
Mrs Okafor likes your time plan. Then she asks two questions.
"Who will do each job? And how much will it cost?"
If you cannot answer, she may say no. A plan with names, prices and reasons is a plan a client can trust.

|---|---|---|---|
| Materials | Used up | Printing a guide | Amount x price each. The x sign means multiply. |
| Physical resources | Used again | Hire of 2 laptops | Amount x price each |
| Personnel | People's time | A developer for 20 hours | Hours x pay for 1 hour |

Worked example: a cost plan
| Item | Kind | Amount | Price each | Cost | Running total |
|---|---|---|---|---|---|
| Laptop hire | Physical resource | 2 | 30 | 2 x 30 = 60 | 60 |
| Printing | Materials | 1 | 20 | 1 x 20 = 20 | 60 + 20 = 80 |
| Developer time | Personnel | 20 hours | 15 | 20 x 15 = 300 | 80 + 300 = 380 |
| Tester time | Personnel | 8 hours | 15 | 8 x 15 = 120 | 380 + 120 = 500 |
