Answer: 5.25x + 12

Let the number be x

x number of quarters means = x * 1/4

x/4

Half the number of ten - dollar bills as quarters

This implies that, ten - dollar as quarters = 1/2 * 10 *x

= 10x/2

5x

The expression is x/4 + 12 + 5x


\begin{gathered} \text{The expression = }(x)/(4)\text{ + 12 + 5x} \\ \text{= 0.25x + 12 + 5x} \\ \text{Collect the like terms} \\ 0.25x\text{ + 5x + 12} \\ 5.25x\text{ + 12} \end{gathered}

The expression is 5.25x + 12
