Answer 1

To earn at least $122.50 per day, Wing Ko must replace 5 watch bands

Here, we want to find the number of bands that Wing Ko must replace to earn at least $122.50 per day

Let the number of watch bands be x

Using mathematical relatio to represent this inequality, we have;

$\begin{gathered} 24.\text{ 6 }\times\text{ x }\ge\text{ 122.50} \\ 24.6x\text{ }\ge\text{ 122.50} \\ \\ x\text{ }\ge\text{ }\frac{122.5}{24.6} \\ \\ x\text{ }\ge\text{ 4.97} \\ \\ x\text{ }\ge\text{ 5} \end{gathered}$
