2.
(a) Use \(A = \dfrac{6B}{8}\) to find the value of \(A\) when \(B = 34\). [2]
(b)
The cost to hire a bike is given by the formula:
Cost = £14 + £5.75 × number of whole days hired
Tom has £80 to spend.
He wants to hire a bike for as many days as possible.

| Scheme | Marks | Comments |
|---|---|---|
| (34 × 6) ÷ 8 | M1 | May be seen in stages. |
| = 25.5 | A1 | If no marks, award SC1 for sight of 204. |
| Scheme | Marks | Comments |
|---|---|---|
| (80 – 14) ÷ 5.75 | M2 | May be implied by 14 + 5.75 × 11 = 77.25 from trials M1 for a correct trial of 14 + 5.75 × \(n\) where \(n \gt 1\) or M1 for 80 – 14 |
| 11 | A1 | CAO An answer or 11.4(7…) or 11.5 implies M2 A0. 14 + 5.75 × 11 = 77.25 gains M2 A0 unless 11 days is indicated as their answer. |
