$\left[\begin{array}{ccc}22&18\end{array}\right]\times\left[\begin{array}{cccc}5&18&32&40\\25&40&38&12\end{array}\right]\\\\=\left[\begin{array}{cccc}22\cdot5+18\cdot25&22\cdot18+18\cdot40&22\cdot32+18\cdot38&22\cdot40+18\cdot12\end{array}\right]\\\\=\left[\begin{array}{cccc}560&1116&1388&1096\end{array}\right]$

second question:

January: 32 · 22 + 38 · 18 = 704 + 684 = 1388

December: 18 · 22 + 40 · 18 = 396 + 720 = 1116

1388 - 1116 = 272

Answer: $272.

Paul, Colin and Brian are waiters.

Reptile [31]

Paul receives 2 portions, which equals to 7.9 * 2 = 15.8

Colin receives 3 portions , this equals to 7.9 * 3 = 23.7

the difference between the 2 portions is 23.7 - 15.8 = 7.9

hence, Colin receives £7.9 over Paul
