5 The total cost of a taxi ride is calculated by adding
a fixed charge of £4
and
a charge of £2 per mile.
Write a formula to work out the total cost, £\(C\), of a journey of \(m\) miles. [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(2m + 4\) or \(2 \times m + 4\) | B2 | oe B1 \(2m\) or \(m2\) or \(200m + 400\) or \(km + 4\) with k an integer, \(k \ne 0\) or 2 |
Additional guidance
| Ignore any attempt to substitute a value for \(m\) after \(2m\) seen for B1 | |
| Condone \(m2 + 4\) (not testing simplification) | B2 |
| Accept use of another letter for \(m\) other than \(c\) eg1 \(2x + 4\) eg2 \(2c + 4\) | B2 B0 |
| Condone inclusion of £ sign for B1 eg1 £\(2m + 4\) eg2 £\(2m\) | B1 B1 |
