(b) Work out the value of \(\;2p^2 + 3m\) (2)
There are 6 eggs in a small box of eggs.
There are 12 eggs in a large box of eggs.
Alex buys \(g\) small boxes of eggs and \(h\) large boxes of eggs.
He buys a total of \(T\) eggs.
(c) Write down a formula for \(T\) in terms of \(g\) and \(h\). (3)

Notes
B3: for \(T = 6g + 12h\) oe
(B2 for \(6g + 12h\) oe or \(T = 6g + ah\) or \(T = bg + 12h\) or \(T = 12g + 6h\) oe)
(B1 for \(6g + ah\) or \(bg + 12h\) or \(12g + 6h\) or for an incorrect expression in \(g\) and \(h\) eg \(T = g + h\))
