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
[tex]\begin{gathered} \text{The expression = }\frac{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}[/tex]The expression is 5.25x + 12
