9 A shop sells packets of envelopes.
There are 5 envelopes in a small packet.
There are 20 envelopes in a large packet.
There is a total of \(T\) envelopes in \(x\) small packets and \(y\) large packets.
Write down a formula for \(T\) in terms of \(x\) and \(y\). (3)
| Answer | Mark | Notes |
|---|---|---|
| \(T = 5x + 20y\) | 3 | B3 for \(T = 5x + 20y\) oe (B2 for \(5x + 20y\) or \(T = 5x + y\) or \(T = x + 20y\) or \(T = 20x + 5y\)) (B1 for \(T\) = a two term linear expression in \(x\) and \(y\), or \(5x + y\) or \(x + 20y\)) |
